A friend from work has this “pistol” and is looking for info from anyone anywhere that might shine a light on what it is. What I do know is it is a single shot 22 and there are absolutely no markings on it anywhere. (Not even a serial number) He believes it may have been a pattern for S&W as his grandfather was a pattern maker for a company that did work for S&W and that my friends is as much as I know! Can you fill in the blanks with more details? Have an idea of value? Is it legal?
