Okay, here we go. One reliable source states that US Revolver Company is a trade name used by Iver Johnson yet another suggest that this trade name was used by the Otis A. Smith Company. Either could be true, both sources are well respected in the industry, they however will go un-named here. Anyway the Otis A. Smith Company manufactured a large number of pistols and fine carpentry tools from 1884 thru about 1917. Poor records were kept and they were manufactured under an assortment of trade names so identification is iffy at best. Hell, he could have manufactured a run of pistols for Iver Johnson, thus leading to the confusion today. Without Mr. Peabody's Wayback Machine we may never know.
