Hi Rick,
I will be happy to show these. They are stamped, and a couple are inlaid with either copper or a red gold. The marks are attributed to Peter Kull the last picture is from "Geschichte Der Solinger Klingenindustrie" by R. Cronau. I think I did post this one before on the old forum. If you want any other close ups I will be more than happy to show this one off, crude they say Hummph...
