So we just got this in a couple hours ago. I have determined it was made by a guy/company named "Pieper". Apparently Steyr was affiliated with them at some point however there are no Steyr markings on the gun. There are Belgian proof marks including "depose". Its chambered in 25. I looked up Pieper but no model that I have found is like it. The barrel is not a break top. It also came with the pictured coin purse and the German registration papers (from 1919). Its in excellent condition and even has two mags. Can you guys tell me anything about it? Value? Thanks
