H&R manufactured a series of single-barrel break-open shotguns, between 1908 and 1942. Chambered for various gauges, barrel lengths and chokes. Finishes were blued with walnut stocks. Little collector interest in these guns. If in sound condition are desirable as shooters only. They are Models 3, 5, 6, 7, 8, 9, as well as hinged-frame folding design.
