Here's an image from a 1920s(I think) Brenneke catalogue of the Musselshell lockup and following are proofmark pics of Mark Baumgarten's Brenneke safety drilling with Poldi tubes. There's an article in GGCA publication No. 22(Summer 2004) detailing Mark's father and the receiver.
Anyone know what currency units the "Cr. 1000" might be?
Interesting that some function of the tube making was performed by Valentin Christoph Schilling on this Suhl made drilling. I wonder if ole Konrad Heym was still involved. The rifled tube at 65cm is a good deal shorter than the 72cm scattergun tubes.
