Ah, I use odd terms from time to time:


1/2 pipe where I think Merkel & Simson had the full pipe, but I may be thinking post WWII.

Sempert & Krieghoff may have been around 31k and I'm not sure on Krieghoff. It may be that the sporting arms division was Sempert & Krieghoff while Krieghoff filled the military contract?

Kind regards,
