Looking through the awesome new books, I think I see a slight mistake. Page 548 says the bolt release lever is marked 'k' to denote a karabiner part. I believe the marking denotes a Luck & Wagner supplied part. IIRC, the only parts that could carry the 'k' (usually capitalized) for karabiner would be stocks, cleaning rods, and rear sight ramps. These being the only parts not compatible with the gewehr system.
Either way, excellent information and images. Page 713 is one of the coolest period pics I've seen. Happy to see my duv42 867e in there.
