Hi Franck.
As Steve has written, I would expect that number to be 00708335. The zero between the digit 7 and 8 was often omitted in paperwork, even in official engine documents. In this case, the / instead of the zero is interesting. If Steve has got many examples of this in his records then that is helpful. However, there is no doubt in my mind that this will have been an 8-digit serial number, 00708335 which should be a Genshagen DB 605 built in June 1944.
The 1014 number would also tie-in with this engine being a DB 605 AS version and so it would be the 1014th AS built, and I expect that this engine was built new as an AS. The motor serial number and the /AS number 1014 both fit into the sequences.
Was it built as an ASM? This is difficult to know without the original engine log card. However, there are only minor differences on the engine for the fitting of the MW50, and many early AS engines will have been modified for use with MW 50. The Daimler-Benz PROVISIONAL instructions for modification of the DB 605 A and AS in the Bf 109 G with MW50 were dated 6.5.44 and were properly issued on 20.6.44.
The instructions state that the engine type with the simple modifications is changed from AS to ASM, and A to AM.
I hope that information is useful.

Cheers

Chris

Thank you Chris.

The recently recovered Dunai-made DB 605A, fitted to a Hungarian-made Bf 109Ga-6, has a large red M in front of the construction number applied on the engine side (00400342). What is the meaning of the red M? Note: it's not Methanol. Thanks.

Hi Dénes,

Yes, that red painted "M" is interesting. Unfortunately, I have not found an explanation in the Instand or Reparatur-Anleitung documents. 00400342 would seem to be built in early October 1943, so it could have been built to the standard for full power rating. Also, it might possibly also have had repair or overhaul. But these are just thoughts, I do not have any more info.
BTW, how do you know it was not a later modified Methanol engine please?
Best Wishes,

SM
