I saw this, can't afford any more guns for a while, and got it as fast as my fingers could pound the keyboard.

It is a Nagel & Menz, Hofbuchesenmaker to Kaiser and King Strasbourg U Baden drilling from 1887 and bears a noble's crest.

It's 16ga and possibly 10.5X47R, and the bores are mirror. I think I can modify 45-70 brass to get the rifle shooting.
