Hi Ed,
I'm working on more inside-info on arms production. Have a good documented view of the Karlsruhe ammunition production, administration, education and even the company restaurant.
If all goes well, I'll have some more in my hands next week. It will mainly be photographic evidence of pre-WW1 German rifle-manufacture, along with some contemporary 1912 ads from Mauser and Krieghoff, to name a few.
This is one of the pictures the seller sent me, showing 2 pages of the publication, with a photo of Mauser riflestock production.
