Mercedes-Benz DB605 Late War Documentation

[schwarze-man]

Members may be interested that in the last 30 years or so, the original technical documentation of WW2 German Aero-Engines has become much more widely available and so, better understood by everyone with an interest in the subject. This has mainly been due to the tremendous efforts of enthusiasts and technical specialists. The documentation has now reached a high point of availability on the Internet and also, through reproduction that is commercially available. However, there are serious gaps in the documentation of some late war versions of the DB605. This documentation would include anything that references the subject engine types. I would like to use this post as a request to discuss this further with interested members of this forum.
Some of this documentation may be held by individual enthusiasts, by those who do not know what it is and also, in official records or libraries or even, in bric a brac shops. Whatever the case, it would benefit everyone if this information is discovered and not lost. The information would include, Engine Handbook, Parts List, Overhaul Manual and other titles, including manufacturing instructions. Complicating the discovery of such material is the fact that many official German technical documents in the late war period after Autumn '44 were issued without the drawings or illustration that would often normally show their subject. Fortunately, the engine designation, such as DB605D, will often feature in the title page and document references and so make the discovery possible.
From my personal perspective, and to the best of my knowledge, there are important gaps in the documentation of the following DB605 types:
DB605DM (summer '44).
DB605ASB ('45).
DB605ASC ('45).

IMO, these are the engines that lack the most information. They are particularly important because they were used in late versions of the Bf109 that were used in the late war fighting. The DB605DM was the initial equipment of the Bf109K4 but, I believe production of this engine was severely effected by targeted Allied bombing of its production plant. Subsequently, the revised DB605DB/DC came into production in late '44. There are details known for the DB/DC but, I would be happy to hear from anyone with information about those engines and compare notes.
The DB605ASB/ASC are lacking any technical paperwork that I know of.

Finally, I know that there are "Data Sheets" for these engines and other modern descriptions but, the information that I would like to uncover is the original material from '44/'45.
Happy to communicate on this forum or by private message. I will honour any info given in agreed confidence or limited as agreed.
Thanks for any help!
