It passed thru the Suhl Proof Facility in June of 1940 and has what looks to be a copper dim light flip-up sight. I have seen those before & will have to dig a little. It was made for cold climate use per the Asian Water Buffalo horn triggerbow guard. It was made by Bernhard Merkel and I am not sure of the engraver.
