German Mystery Gun “Ant. Bennsman”

on most European guns- the country of origin proof marks are pretty easy to recognize-
max loads and date id's take some study- but, it would seem that having the basics would be a good idea for folks who like these old guns

some starting points

I'm not convinced the barrels are hot blued. The underside photos certainly don't exhibit the black, shiny finish I would expect to see on a hot blued surface. Whatever the case, the 'ring' test will give you a pretty good idea of the soundness of soldered joint integrity.
