Neighbor came over today with a 1960's H(erbert) Schmidt nickel .22 single action Model 21S pistol. He asked if I would like it since he is not a gun person. I asked how much, and he said I could have it, he just wanted it out of the house. Seems his dad passed a while back and he found it in the belongings. It is marked .22 LR on the top of the barrel. I did some research and these pistols had both a LR and Magnum cylinder. The cylinder on this is 1 3/8" long....just want to make sure the cylinder is .22 LR instead of Magnum....also anyone with knowledge of this pistol would be appreciated...Thanks
