I have an old 1950's Browning Superposed in 12ga. I was shooting it a year or so ago and all of a sudden it would not fire. My father took it to a local guy near Lexington, VA and he said something was broken that let me shoot the bottom barrel first, so I had to shoot top barrel then let gravity set the bottom barrel. He also said it he could not find a replacement part (this was all told to me by my father). My question is does anyone know of a gunsmith in Virginia who works on Superposeds and could get replacement parts?
