List of DB 605A engine construction numbers?

[S Sheflin]

Thank you Gabor,
I am always excited to add more Motornummern to my files.
Respectfully,

Which manufacturer built DB 605A engines, from late 1942, in the following constr. no. batch: "700/XXX"? Many thanks.

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)
Factory code hsq
Engine serial numbers:
7xxxx - A-1
007xxxx - A-1, B-1, AM, ASM, AS0, ASM0, G
117xxxx - D, DB, DM, DM0"

Cheers

SM

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.

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.
