Browning Black Powder
I also have one, brought it back Europe in 77, bought at an American Rod and Gun Club. Its the Centenial Model,# 913 out of 1000 and has a bust medalion in the butt of Johnathen Browning. Its a .50, steel trim and the most beautiful figured stock. They really did a fine job. I kept it un-fired for years...but then broke down, and even for a beginer..it shot great. No regrets.
