One of my managers at work was given some old shotguns some years ago by his grandfather. He asked me to help him find some info on one of them which he was told was the oldest in the collection, so I come to GT in search of some answers. The gun is a seemingly old Side by Side 12 ga. My friend was told that it was purchased by his great grandfather in Germany after WWI. The only markings I could find on the gun were: JP Sauer and Sohn, Sohl and the number 55094 which I am assuming is a serial number. My buddy doesn't really believe the gun is as old as he was told, so he asked me to help prove or disprove the story. The reciever of the gun has alot of engraving on it that appears to be factory. Does anyone know much about these guns?
