Utah,

The .410 was not readily available in the states until 1915. The 1st American gun chambered for it was the Stevens single shot, as far as I can tell. It was chambered for the 2" inch 410. There were a host of single shots that followed. The 1st American sxs was Parker in 1921 or there abouts.

Is there a model name like Peerless on the gun? Have checked the chamber length?
