Hi Everyone!

I am pleased to say that I have made further analysis of the early 5 digit DB 601 and DB 605 engine serial numbers. My details in reply #70 can change a little in that the blocks of engine numbers for the DB 601 A, the DB 601 N and the DB 601 E/F can be better grouped. The allocation of production plants is made by my correlation to production figures by date from the records and the excellent assessments by Tomislav. There are a few unusual engine serial numbers to be found in the data but these amount to only about 1% of the sample and are obvious errors or numbers that bear little relation to the overall data.
As I have previously noted, I have found difficulty with the total range of possible numbers in the 5 digit blocks, which far exceeds the engine production. This obviously implies that not all numbers were used, and presumably many block numbers were partly unused. So to give some help I am listing the blocks that are in the data.
Further difficulty arises with the DB 601 N engine that is not always annotated in the data. I have listed the blocks where this type is known but some will be in the DB 601 A blocks. The DB 601 E engines are quite easily identified with the Bf 109 F-3/4 and these are listed, although the sample numbers are small.


DB 601 A.

Marienfeld, Werk 90.
10xxx, 11xxx.

NIMO, Brunswick.
20xxx, 21xxx, 22xxx.

Henschel, Kassel.
30xxx, 31xxx.

Genshagen.
60xxx, 61xxx, 62xxx, 63xxx, 64xxx, 65xxx, 66xxx.


Known DB 601 N in Blocks.

NIMO, Brunswick.
21xxx, 22xxx.

Henschel, Kassel.
32xxx.

Genshagen.
66xxx, 67xxx.


DB 601 E.

Possibly Marienfeld, Werk 90.

The next post by me will carry-on with the 5 digit DB 605 A/B blocks.
Cheers
