Smith & Wesson model 52 .22 Jet revolver with a 6" barrel. This is a very interesting piece as it has chamber inserts to size the larger cylinder down to .22lr. The barrel is marked .22 Magnum and the cylinder is for .22 Jet then the three inserts are for .22lf. More inserts are commercially available and inexpensive. The gun itself is in great shape. Unfortunately, there are only three inserts, and not six. It comes in a presentation box that is in fair condition.
