Gentlemen, please consider that the DB 605 engine was also produced in Italy. It's missing from the list.

Yes, I have Fiat production at 334 DB605. The only engine ID I have is the restored Aer Macchi MC205 Veltro at Varese. This is listed with "Fiat Mercedes Benz DB605A 76679". I would be interested in any other info on the Fiat production. Cheers

Hi Schwarze-man,
The only reference I have to Fiat-built DB 605’s is from CEA 268. It lists Bf109G-6/R2 (WNr. 230500), marked 65+, as being found crashed on 45/03/30 NE of “Grave.” It was powered by DB 605 A-1 (MNr. 46773) and designated as being built by Fiat.
Respectfully,

Thank you Steve, that is good info. Apparently, two FIAT DB605 with what seems to be German production numbering. Not impossible that DB gave the numbers to their licensee to use. You might see I have asked on another thread about Macchi 202/205 engines, to try for any more info. On the subject of the Alfa-Romeo DB601, I have worked on one, very nicely made. Cheers

Re: List of DB 605A engine construction numbers?
 
On a side note: are we only discussing DB605 production during the war?
The DB605B was also produced under license here in Sweden just after the war: IIRC production at Bolinder-Munktell and Svenska Flygmotor AB started during the autumn of 1945 and continued until 1948 (this was for the pusher-fighter J21 and the bombers B18B & T18B).
Total production was 800 engines, with serial numbers 2001-2800.

In addition to this we bought a number of German-produced DB605B engines, before production of the improved/corrected variant began here in Sweden.

EDIT (after checking my references):
The initial procurement of German-manufactured engines was made in April, 1943, and consisted of 71 DB605B engines along with VDM propellers and accessories.
The Swedish production (800 units) of the DB605B was split between Bolinder-Munktell (>100 engines) in Eskilstuna, and Svenska Flygmotor AB (<700 engines) in Trollhättan.

Re: List of DB 605A engine construction numbers?
 
Yes 219, I found similar numbers and production details in an online article. I also have the details about the Swedish production standard engines. These are very close in almost every detail to the mid 1943 production DB605B-1. The similarity is so close that I presume the production tooling and the casting moulds were initially supplied by DB. The engine details such as the fuel pumps and magneto etc, seem to be the original German parts, although it is possible that these were also produced. Although the installation of the 605 in Swedish aircraft was specific to the Swedish aircraft, the engine remained, very much, the 1943 DB605, with very minor differences. For instance, there is no provision for the (mid 1944 onwards) MW50 system, the supercharger is the standard 605A/B and, there is no Olschlueder. The later 1944 DB605D differences do not seem to make any appearance in the construction of the post war production engines. In fact, the Swedes are recorded as being very interested in the DB605D engine of a late BF109G/K that flew to Sweden at the end of the war. Members might be interested in one technical difference that is fully detailed in the Swedish 605 manual. The specification for B4 type fuel, 1.42ata/2800U/min/1475PS power is standard. However, if operated on Allied Avgas 100/130, the Boost pressure regulator could be adjusted to give 1.65ata/2800U/min/1700PS. There were no other changes to achieve this power rating. Cheers

Does someone know who was the manufacturer of DB 605A-1 engines whose W.Nr. is in the 80xxx format?
Finally, a long shot - but most important topic for me. The Rumanian I.A.R. Works at Brasov planned to build the DB 605A-1 engine in licence in 1944/1945. Is this factory mentioned in any production plans? Is the planned Werknummer block assigned to it known?

Hello Dénes,
Regarding DB 605 A-1’s manufactured with Motornummern from within the 80xxx series, so far I only have seven:

80238, 80395, 81112, 81242, 81429, 81436, 81436

I show these as being built by Daimler-Benz Motoren, Genshagen Kreis Teltow. One of them, 81112, is confirmed by a Typenschild.

Regarding engine production at Fiat.


"The engine was also produced under license in Italy by FIAT from 1942. The first examples retained the original name DB 605, whereas those produced from 1943 were renamed FIAT RA 1050 RC 58I Tifone,
for a total production of nearly 1750 exemples, mainly used in the fighter aircrafts FIAT G. 55, Macchi C. 205 and Reggiane Re 2005."

Hi Dénes,
Please could you explain your batch number a little for me? Numbers with / are rare and I don't see any number like 700/xxx in the data. In fact, there are only about 17 entries with 6 digit numbers, the vast majority are 5 digit, then 7 digit in early '44 and 9 digit late '44 till end of data early'45.
The only 6 digit with 700xxx I see is 700420. Is that the sort of number you are looking for or, would it be 700/420 in your case?

Cheers

Interestingly, the only six-digit DB 605 A-1 Motornummern that I have in my admittedly-limited database file, that begin with “7,” are a group of eighteen that were shipped to Finland. These range sporadically from 705096 to 708919. There may be others, but I have been unable to enter them into my database file yet.

Hi again,
The manufacturer id that seems to start with or incorporate a "7" in the batch part of engine number (apart from sevens in the actual serial) is as Tomislav listed earlier:
"Daimler-Benz Motoren GmbH (Genshagen Kreis Teltow)

Engine serial numbers:

007xxxx - A-1, B-1, AM, ASM, AS0, ASM0, G

I meant exclusively the engine construction numbers that include a slash (/). I enclose one such example, DB 605 No. 239/0118, from a Hungarian document from February 1944 (P.S. sorry, cannot find the image posting button anymore).

Hi again Dénes,
The use of the forward-slash (/) in the engine Werk-Nr is rare in all the 650+ engine database. There are only two examples of a / in that database and, they are 007/01188 and another early but obviously very corrupted one with 12 figures, 311002A/205-4.
The 007/01188 seems to be a mistake as it falls within many other engines in that range eg 00700933 that have 8 digit numbers.
The only note I would make, is that in this case the 007 is the manufacturer id and the 00933 is the serial number. Possibly the worker accidently added the / in error to the 007/01188 which should have been simply 00701188.
The convention of marking is consistent, the manufacturer id runs directly before the serial number on the engine Werk-Nr, as struck on the Baumusterschild and the many stampings on the engine components.
Also, within the 650 engine data, 007/01188 is the only / after the first 3 digits.
So, sorry that this is not much use.

Re: List of DB 605A engine construction numbers?
 
Hello SM, there are too many occurences when a slash was an integral part of DB 605 A/B engines' construction number to consider it a clerical error. The explanation of this slash is what I am looking for. I will keep "digging" for an answer.

Hallo Dénes,
The / could have been used to demark elements of the series of digits that define a part. In the case of these engine Werk-Nr as defined by DB, they do consist of two parts, the manufacturer id and the production serial number. The id can be a single digit, two, three or four depending on the date and allocated manufacturer. The serial number of the motor is after the id but, there is no / to demark this construction of the full Werk-Nr. This is the evidence from almost all 650+ engines in the database and shows the marking of the Baumusterschild. However, it may be possible that clerical data was recorded differently by other contractors.

SM

Dénes Bernád 5th April 2022 19:13

Re: List of DB 605A engine construction numbers?
 
Dear SM, in these particular cases, the first three digits before the slash (there are too many to tell the slash is an error) are not identical, many of them are unique, so they are certainly not the manufacturer's identification, but rather an odd serial number, divided by the slash.
I need to "dig in" more, perhaps I will find a clue one day.

Re: List of DB 605A engine construction numbers?
 
Hi everyone,
I am pleased to say that I have more results about the DB605 engine serial number analysis from the loss records of the 800+ engines supplied by Matti, Tomislav and otherb contributors.
So far in my posts (mainly about #68 to #70) I have covered the DB600/601 engines and I think the numbers stack-up well. However, although the further numbers for the DB605 are well represented, my analysis of the DB605 5-Digit serial numbers is not satisfactory. Simply put, the numbers of engines indicated by the 5-digit block numbers seems too high. I suspect that there may be gaps in the serial number allocations that I cannot identify.
So, I decided to consider the later DB605D engines in the loss reports and I quickly saw how well defined they are, for the period Nov '44 to Jan '45. I will report those details later.
A by-product of the 605D study was a better definition of the 605A serial numbers for the new 8-digit numbering system that was introduced in about early 1943. The 8-digit numbers have the first three digits for a makers id, eg 007 for Genshagen, followed by a five-digit number for the sequential engine serial number starting 00001. So, the first engine in this new numbering from Genshagen was 00700001.
I was able to corelate the BIOS report of engine manufacture quantities, dates and plants accurately and easily confirm data against the loss table engine numbers and the inferred production numbers.
There are some interesting relationships between engine production dates and the date of the loss. Generally, the first date of loss of a series in the data will be a fairly early serial number, but it won't be the first made. The vagaries of engine supply, airframe build date and then use mess it all up. However, the dates of some losses were fairly close to manufacture and, with these series here of over 10,000 engines, there is some good correlation.
There are some errors in the data I have to work with here, possibly 1%. I think that I can accurately correct 50% of those but some are just errors that cannot be corrected accurately. Fortunately, the data is large enough to not use the info with errors.
The number of engines in this 8-digit engine serial number analysis covers approx 25,000 DB605A engines built by six manufacturing plants in the period. There is one plant with 10,000+ engines, two with 6,000+ and two with less than 2,000.
I will list the details on my next post.

Cheers

SM

Re: List of DB 605A engine construction numbers?
 
The 8-digit DB605 serial numbering appears to have been introduced in early 1943. The exact dates seem to vary with different production plants, calculated from the dates of the loss reports and the records of production figures in the BIOS report. This probably reflects the varied dates for completion of previous batches in the 5-digit serial numbering system. Very helpfully, the loss reports of the Bf 109 airframes with dates, types and sub-types gives considerable information about the engine type, although only the engine serial numbers are given. The BIOS reports of engine manufacture lack any detail of engine models produced, other than "601, 603, or 605" and the monthly production figures. The BIOS written report does give further details of factors effecting individual plants and this is helpful in some cases. Nonetheless, the details that I have extracted are accurate in respect of the overall production.
I will attempt to present a similar table to that produced earlier by Tomislav. It must be borne in mind that the dates of production are estimates from the loss records and production records. Additional complications occur where engines were held in store and also overhauled at central plants.

Re: List of DB 605A engine construction numbers?
 
These listed tables below are estimates compiled from data in Bf 109 loss reports that were provided by contributor Matti. These details relate to DB 605A engines produced with the 8-digit numbering system introduced in approximately early 1943, superceeding the previous 5-digit numbering.
The 8-digit engine sample are approximately 450 sets of data. Only data from engines in the data set is used and so, other engine production plants are not shown.
After approximately Feb 1944, these engines will include some DB 605 AS versions and, after May 1944 engines built for MW50 ratings.

Many thanks, SM, for the updated production table.
My question is: did you include the DB 605B production as well? The reason is that those two sub-types were almost identical, only the reduction gear made the difference.

schwarze-man 30th July 2022 18:32

Re: List of DB 605A engine construction numbers?
 
Hi Dénes,
Well, the data of DB601, 603 and 605 engines in Bf 110 and Me 410 losses that was also generously supplied by Matti, covers some 140 engines of those types. However, only eight of those engines are 8-digit serial number DB605 engines and they all fall within the scope of my data above. The other 132-odd engines are earlier 5-digit serial numbered DB601 and DB605 engines. As I have commented, the 5-digit serial DB605 engines have presented difficulties with my earlier analysis, as the numbers (total of block numbers) seem to be far too large. However, I might revisit the DB605 5-digit serial number data again in future, if I can face it!
Pleasingly though, this analysis of the 8-digit serial numbered engines in the loss record data and the BIOS report is very satisfactory. To illustrate how it fits, the BIOS report shows approx 34,700 DB605 engines built in '43 + '44. The engines built in early 1943, before the 8-figure serials, were approx 4,000, that leaves approx 30,700. Then, there are the "other" plants production (from BIOS) that do not appear in the loss report data I have that total approx 6,700, therefore leaving approx 24,000 engines in the blocks that fall within the loss reports I have worked from. So, this fits with about 95% accuracy.
There are of course many details that nothing short of a complete detailed record of all production and exact types produced when and where could resolve, but that does not exist. The main omissions from my data include DB605 production at "other" plants which the BIOS report lists as "FIAT, Pommersche, Ostmark and Avia" The BIOS report does not mention Swedish production.
So, overall I am pleased with this work. It should allow anyone researching an RLM 8-digit DB605 engine serial number to find a cross reference with 80% success. X-referencing with the BIOS report should give an accurate production date, within about one-month accuracy.
It would be great to see further info about the "other" plants and a better understanding of the earlier 5-digit DB605 engine production is needed.

Cheers

SM

PS. I have since noticed that I have made an error in the BIOS production report. The "Pommersche, Ostmark and Avia" production is listed as just DB 603. This makes a difference of about 6,300 engines on my DB 605 figures. However, the figures above will be revised and updated. This also leaves a better situation in that, there are no known "other" DB 605 production plants, at least no others that show in the BIOS report.
Also, the Bf 110 G using the DB 605 B engines was built in about 3,250 examples during 1943 and 1944. These would have required about 6,500 DB 605 B engines, that came from the totals of DB 605 production.
I will revise the figures and I can see some further revision that can be applied due to my data on the DB 605 D production in the later part of 1944.

schwarze-man 31st July 2022 19:34

Re: List of DB 605A engine construction numbers?
 
As I indicated in my PS to my post #106, I made a mistake in including some engine production figures from other plants producing the DB 603. I have now reviewed the data. There are now allowances made for the change-over to production of the DB 605 D engine at two plants, first at Henschel where the DB 605 D is estimated to have started production properly in Aug '44 and at Genshagen where DB 605 D production may have started at the beginning of Nov '44. These changes reflect on the dates for the various estimated start of 8-digit engine serial numbering due to the correlation of the engine loss data and the BIOS report engine production figures. In addition, I have tried to improve the accuracy of the figures given.

Pleasingly, this analysis of the 8-digit serial numbered DB 605 engines in the loss record data and the BIOS production report is very satisfactory. To illustrate how it fits, the BIOS report shows approx 34,700 DB605 engines built in '43 + '44. The engines built in early 1943, before the 8-figure serials, were approx 4,300, that leaves approx 30,400. Then, there are the engines from Henschel and Genshagen that were produced as DB 605 D, total 3,700 leaving approx 26,700 as the gross production figure of DB 605 A/B/AS (and MW50 after 5/44) engines in the 8-digit serial blocks till 12/44. If we take just the highest recorded 8-digit serial numbers from loss reports, that is 24,740. That shows a figure of over 92% which is very good. If the estimated production figures are used, the correlation is over 97.5%.
The value of this analysis is, I think, that anyone with a copy of the BIOS report monthly production figures can take almost any 8-digit DB 605 serial number and identify both the manufacture plant and the date of manufacture, accurate to possibly one week. If anyone has an 8-digit DB 605 serial number, they can try me here and I will refer to the BIOS data and give a reply.

schwarze-man 2nd August 2022 13:07

Re: List of DB 605A engine construction numbers?
 
Well,
No takers on the 8-digit serial number dates?
OK, I can do one to illustrate. How about, 00706308.
Here is the 007 8-digit code id:

"Daimler-Benz Motoren GmbH (Genshagen Kreis Teltow)
Factory code hsq
Engine serial numbers:
00700001
First in data 00700207. Last in data 00711041. Production data 11,200.
Series started estimate 5/43, Finished 10/44."


Here is the loss report from the data for 00706308:

"10/10/44. 9.JG52. Bf 109 G-6. 440576. White 8. Motor 00706308."

So we can refer to the BIOS report and the monthly production figures for DB605 at Genshagen 8-digit codes produced between 5/43 and 10/44.
These are:
5/43-500. 6/43-566. 7/43-469. 8/43-359. 9/43-459. 10/43-578. 11/43-390. 12/43-587. 1/44-500. 2/44-640. 3/44-730. 4/44-862. 5/44-851. 6/44-862. 7/44-1040. 8/44-450. 9/44-700. 10/44-410.

So, starting with 00700001 on 01/05/43, we can add the months' output to get 5778 at end 3/44. Dividing the production in 4/44 by 30 days gives just under 29 engines per day, giving another 19 days to add to reach 00706308 and therefore a production date of 19/4/44.
Also, to compare the other way, working back from the completion of production at end 10/44 with 11200 as the estimated final production number, subtracting the monthly production figures we get down to 6887 at the beginning 5/44. Again allowing the 29 a day we get another 20 days back to reach 06308 so, a production date of 10/4/44.
Well, that is the limit of the accuracy here, between the 10th and the 19th of April 1944.
Now, it would be possible to fudge these figures by manipulating the start and finish dates of production and/or the estimated production figures but, this has not been done. These are pure figures. The production quantities are from the BIOS reports, the start and finish dates are a partly from production data and the loss reports data.

Thank you Steve!
I feel that these 8-figure engine serial numbers and production data, correlated with the significant loss report database from Matti Salonen is an accurate tool for the DB605 researcher. I am grateful for your support. If you find any questions or wish to make a point, please jump in!

Cheers

Re: List of DB 605A engine construction numbers?
 
Hello,


regarding Reggiane aircraft, so far the following DB605/Fiat RA1050 engines were identified, according to Ali d'Italia nr. 16 and Regia Aeronautica papers:


Aircraft M.M. - Engine M.M.'s
494 - 7738, 47907, 47993
092343 - 47881/001
092345 - RA 47968
092346 - 47958/078, 48014 (or 48018)
092348 - RA 47964
092354 - 48028 (or 48208)
092358 - 48115/235
096102 - 48153/273


Notes:

- where I typed RA means the document mentions explicitely Fiat.
- There is also a picture of a RE2005 showing engine M.M. 47999.
- The nr. 7738 comes from a picture. It seems it's really a 4 digit number.

Hello tanzebau,
Thank you for your intriguing postings. They do, however, raise a question.
Did Fiat ever produce any DB 605 “AS” versions? I ask because several of your entries have “/xxx” MNr. extensions. Do you think these “extra” digits could be “AS” serial numbers?
On German-made engines, these three or four digit extensions were serialized “AS” modification numbers. In some cases (mainly on Allied Crashed Enemy Aircraft reports), they were also listed as three or four digits added immediately before the actual MNr.
Respectfully,
Steve Sheflin

Hello Steve,


unfortunately I don't have direct access to those specific reports but it's nery unlikely that it means a DB605AS used on RE2005's. It looks more like a progressive number from 47880

Re: List of DB 605A engine construction numbers?
 
It certainly seems that the Alfa Romeo production is missing from the Allied BIOS reports, similar to the Swedish production. Also, the A.R. 1000 DB601 5-digit numbers cover a large range of around 10,000 numbers in those examples, I think there is little doubt they must have been allocated small production block-numbers in that range.
The FIAT DB 605 is listed as 120 produced in '43 and 214 in '44 for a total of 334. The example block numbers given above range about 445 examples (ignoring the possible high number), which almost looks like it could be a continuous "block". There might be the possibility of the continued 605 production at FIAT in '45 not being reflected by the BIOS recording?
The whole subject of AS engine production is interesting. I have not found much detail about production but, the photographic record shows a lot of AS powered aircraft! There are one or two quotes about AS engines being built within the normal (German) 605 A production blocks, as though they made short runs of AS versions.
Thanks for the info everyone!

Thank you HGabor,
I think these are all Bf 109 G-2 with DB 605 A engines.
Cheers

Yes, they were from a test

Interesting, and an early 109G test it would seem?
I trawled through the 605 loss data that I have but the closest to those engine numbers I have is one about two engines apart, which is close!
There is though 27428 listed as lost as late as 8 Feb '45 in a G-14, which quite a survivor, and would have been rebuilt as an 1800 horsepower AM by then.
Those 25xxx engines are possibly NiMo production, the 76/77xxx probably Genshagen. I know an early Genshagen 77xxx 605A that has a SKODA made crankcase (Kurbelgehause), complete with the SKODA cast-in badge.
There are many major parts from sub contractors. I have seen RENAULT made 605A cylinderblocks with the big Renault diamond shaped badge cast in.

Hi Steve,
I am very interested in the production of the DB 605 AS. I have a test report of the prototype Bf 109 G-5AS, W.Nr 26108, test flown on 22/12/1943.
The engine was DB 605 AS-0 W.Nr 00702626.
This was a first-series production engine (the -0) from DB Genshagen.
I will look at the production date and come back a little later.
As the report is an official write-up, the engine number is likely as shown on the engine plate. However, I realise there might have been other numbers in the production contracts, but I have no useful info about that.
Cheers

Chris
