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.
