If it is not marked on the gun, you will have to measure it. The most probably calibers for an H&R revolver are .22, .32, and .38. A standard lead pencil will not go into the barrel of a .22, fit fairly well into a .32, and be loose in a .38, but don't run out to buy ammunition based on this estimation. Let a gunsmith or experienced dealer see the gun and recommend the proper ammunition (or recommend that it not be fired at all!). That patent date, alone, appears on the H&R Model 1 revolver, which is a single-action revolver with bird's head grip and spur trigger. It was chambered in both .32 Rimfire and .38 Rimfire. The ammunition is obsolete. firstname.lastname@example.org
