I was given a revolver today. ( sorry no camera ) Its is a small frame gun with HS model 11 stamped on the bottom of the grip frame. It has made in Germany and .22lr stamped on the barrel. It has white plastic grips with HS on them. Is this an old High Standard revolver? It's blue with a 4 inch barrel. I believe it is in the original box, but the only markings on the box is a hand written HS 11. The cyclinder does not swing out and it is loaded on the right hand side of the cyclinder. Any ideas?
