Thanks for that letter, I am saving that for my library. Thats an awesome piece of history right there. I tried to do a google translator for the list of parts and some do not make sense to me.

Zubringer = feeder ? Magazine follower?
Abzugshebel = deliver lever ? Maybe the trigger lever in the sideplate?

I believe the Kammerfangstuecke is the extractor, Schlagbolzen is the firing pin, Sicherungsriegel is the safety block, the Sicherungshebel is the safety lever and the Deckplatte is the sideplate. At least I think those are the correct meanings.

However, I still have the same question, how can these individual pieces be identified from standard Erfurt made parts? Is there even a way to identify them? In the Third Reich the subcontracted parts usually had a manufacturer code and/or a waffenamt that would identify the part. Or at least show it was not manufactured by the main manufacturer. Things like K98 barrels could have a code from the factory where made and the bolts could have different waffenamts, such as FN made bolts distributed to other factories. I am guessing that WW1 subcontracted parts did not necessarily have these type markings.
