Hey folks, i recently acquired a 16 ga single shot shotgun. I can tell its old by the wood but i dont even know what kind it is. It has "Special" stamped in the left side of the reciever housing. the only other "marking" it has is a 31 that i found after taking the barrel off. It was on the under side of the barrel. If anyone could help me identify this shotgun I would sure appreciate it.
