No problem at all sir, there’s always something to learn, that’s what makes these old guns so interesting. I find myself quite lost on topics outside of Mauser very quickly!

Now that Kettner you dug up.. I really like that! I’m a sucker for a Mauser Stützen, I have a Sauer very similar to it.

I’m really curious to see what direction the OP decides to go, it would be very hard for me to nail one down, I have at least a dozen Mausers ideas I’d have to sort though!
