I've spent a great deal of time tracking the workmen who left Hoffman Arms Company and went out on their own. I'm not sure Frank Hoffman ever made a rifle so I've not spent a lot of time looking for his work. The last one that I know of, and one I'm missing is John Wright. I have one of his rifles cornered but not captured.

Men who worked at Hoffmans and made rifles later were,
James V. Howe
John Dubiel
Eric Johnson
Harvey Rodgers
John Wright
