List of DB 605A engine construction numbers?

Really useful list, thank you for shearing!
In fact the upper mentioned picture of Bulgarian DB 605 is almost the single clue we have in our effort to identify the plane (thanks Denes). So any help is appreciated!

I confirm the conclusion, that Gyor made 109s were originally equipped with 00400xxx-series engines.

And I attach a little list of spare engines, delivered to Bulgaria.

Another DB605 in the NASM collection is 25898. No dataplate, but in the stamping on the block ( similar to the images I posted of the DB603s above ) is a 'B' then a space followed by an 'R7' and another space followed by '3456'. The white painted 25898 B is also on the side of the block.

The stamping looks like this 25898B R7 3456

There is no aircraft associated with the engine.

Look at the box in the picture i posted a little up. That could explain the R7 3456 number

Hi everyone!
Just another DB605A identity with manufacturer to add to the jigsaw.
I have a genuine alloy identity plate that is from an unknown recovery.
Here are the details:
Gerat-Nr 9 605 A 1
Werk-Nr 35404
hsr

The numbers and hsr are stamped into the metal. I estimate that this was a Henschel-Flugmotorenbau GmbH, Kassel built motor and the number would fit approximately into the Bf109G-2 series. Cheers

Finally since I have room to post, here is the front end of DB603 01602842 with the nose case removed, undergoing preservation and prior to assembly for the He219. You can visualize etched 4 digits on the top of the two gears 2842. The upper one is somewhat difficult to distinguish as 2842 due to the scrolling and almost appears to be 2839 but if you study it closer you will see the 2842.

Thank you for posting the pic of the reduction gear housing Tony! Yes, the numbers electro-etched on those bearing components do show the last 4 digits of the engine serial 2842 IMO. The question of the 2826 stamp on the case adjacent to the ID plate remains open. In my experience, re-allocated components on the DB engines had the inappropriate number or part of the number lined through and, the new engine number stamped. I have usually seen this on overhauled or repaired engines. The engine component numbering proceedure applied to nearly all components. Small components often only had the last 3 or 4 numbers and on steel parts, this was often electro etched. Fit tolerance and assembly position was marked on all size-fitted parts. I suspect that that crankcase will also have it's number stamped on the front top area, above the reduction gear housing in this photo, but I can't make it out and, as carefully matched parts all the main bearing caps will probably be stamped with the full engine number.
Overall, I can imagine circumstances where this engine crankcase was re-allocated a slightly later build number, but it is pure conjecture. Also, I really would expect the 2826 number to have at least the "26" lined through and the "42" stamped above. Random stamped numbers like that are unusual.
Thanks very much for posting these pics!

Indeed, thank you very much, Tony! Very interesting pictures!

Hello,

I have compiled such a table with the known DB605 engine manufactures based on the collected engine data.
Here is what I have so far:

Niedersächsische Motorenwerke GmbH (NMW) "NiMo" (Braunschweig-Querum)
Factory code hss
Engine serial numbers:
2xxxx - A-1, B
20xxxx - A-1
002xxxx - A-1
112xxxx - D

Henschel-Flugmotorenbau GmbH (Kassel)
Factory code hsr
Engine serial numbers:
3xxxx - A-1
011xxxx - A-1, A-4, AM
0111xxxx - D-1, DB, DM, M

Donau-Flugzeugbau (Csepel-Budapest)
Factory code kwn
Engine serial numbers:
4xxxx - A-1
004xxxx - A-1, AM

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

Steyr-Daimler-Puch A.G. (Werk Steyr)
Factory code bnz
Engine serial numbers:
9xxxx - A-1 unconfirmed
019xxxx - A-1
119xxxx - D, DB

There are many DB605 engines in the 1xxxx and 10xxxx range for which I can't confirm the producer. It could be Henschel-Flugmotorenbau GmbH (Kassel) because they continued to use the "1" in their serial numbers of the later produced engines or it could be Daimler-Benz A.G., Werk 40 (Berlin-Marienfelde) cuw because they produced also the DB601 in the 1xxxx range. When compared, the serial number ranges of the DB605 and DB601 producers mostly match which would led me to the conclusion that each engine producer had a designated serial number range which was later extended with a prefix (0, 00, 11..) corresponding to the new engine subtype (for example, all DB605 D engine have the prefix 11).
Of course, all correction and new additions to this data is most welcome.

This is exactly what I was referring to, Tomislav! Many thanks for sharing.
We can now expand and update this list, as info is/will become available.
