I have a 112 year old gun with side by side barrels and exposed hammers that was given to me. It has no serial number and was typical of what some old German craftsman in the Black Forest would have made. The stock is beautiful and the metal work is scrolled and has an early type of patina and a flip up rear sight. The right side barrel is 11 x 51mm and the left side barrel is a Damascus 16 ga. I cut down some 45-70 brass cases and necked them down to 11mm, got a 375 grain bullet mold and made up some rounds with a real low pressure smokeless powder that shoots well. First shot at 50 yds went through the X ring and amazed me and everyone else watching. I purchased some full length brass 16 ga shells and loaded up a few round ball rounds, some buckshot rounds and some #6 birdshot using FFG black powder as Damascus barrels can't take a lot of pressure and were designed for black powder only, they shot well as could be expected too. I did some research and found that collectors will pay $2400 for one and oddly enough the guy that gave it to me tried to buy it back for $300 once he found that it could be fired and that I had created ammo for it.
Uh - sorry pal, I never ask for gifts back, it's really bad form.
