I know of course of the early DM document referenced in the K-4 Handbuch but have never seen it myself.
There is also a hint from MTTAG record of meeting from 20 December 1944 bei DB-UT, which instructs crews to mark engines set to 1.8 ata with a big white 'B' next to the D letter on the Kurbelgehäuse, and a big white 'C' in case of 1.98ata setting. In case of changing the manifold pressure the markings are to be correspondingly modified. Also some GLC datasheets from show only '605D', next to be both 1.8/1.98 ata power curves.
So I am fairly certain the entire D series is the same engine, which saw some minimal changes, boosts.
Herr Baumgartl has an interesting reference in his book 'Lehrunterlangen für die Baumuster DB 601 E-G u. 605 A-D, Flieger-tech. Schule 3 München 67, T.S. 3-2024a, Teil 1. Baumuster Beschreibung für die DB 601 E-G, DB 605 A-B, AS-BS, AM-ASM, D-E, DM. from DBAG Flugmotoren Bd. 149.' This seems to be a rather complete, common manual for these engines on various technical aspects as he references it a lot.
I can't recommend highly enough getting Herr Baumgartl's book as he has done excellent research. The chapters 34-35 of 50 pages is exclusively dedicated to DB 605D development and improvement of performance, which I am sure you would find highly interesting.

Hi Kurfurst,
Thank you for info. Yes, I have these documents. However, I do not think that I have all of the book by Herr Baumgartl. Is it possible that you can give me a help to get this book or a copy. I would appreciate it if you can!
As regards the versions of the D, DM, DB and DC being the same, there are several changes of components that I know of. However, I can agree the basic versions of those engines produced after July '44 are very similar, although with minor changes.
Cheers
