Very interesting shotgun

I have a SXS percussion muzzle loader shot gun. It belonged to my Wife's Grandfather. It is now mine. It is a silver fitted gun with hunting engravings. What is interesting is the maker. It is Ernst Erhardt of Zella Germany. Whom I found to be one of the founders of Rheinmettall of Zella. MG42..FG42 etc, etc. I took pictures. Opinions? Thanks, GaryMoore

Interesting and nice wall hanger. THe trigger guard is actually white brass sometimes know as German silver.
