Classic, beautiful gun. J.P. Sauer & Sohn. Well known German gun maker in business since 1751 (with a little time out for two world wars and one cold war). Located in Shul,Germany until Germany was reunited, now located in Eckerernforde, Germany. I'm sorry but you just don't give enough information to positively identify your gun. All of J.P Sauer & Sohn guns are all high quality guns, and can last for years.
