My buddy wanted me to check my Numeric book for parts on his pistol, I can't even find the gun, or anything like it. Anyway the barrel is loose in the frame and his son told him that the pin that goes through the frame is in two pcs. I will try to post pics later. On the left side of the frame an inlay Says ""Arminius" and has a side profile of a man w/ a beard and a winged had. The crain has "HW7T" on the exposed surface and the serial number on the top, not exposed. The right side says the it was made in Germany. It has other markings, I'll try to get pics. I believe he said that he bought the gun in the mid 70's. Thanks.
