Henry Deringer made all sorts of firearms, from pistols to rifles and muskets for the US military, but seems to be most famous for his 'cute' little pistols, in which his name became synonymous with a 'style' or pattern of handgun. He, an Easterner, was popular in the West as well, that is his rifles and full sized pistols were popular there - mostly in around the .45 to .48 cal. in rifle and many full sized, almost holster pistols, calibre .50 and under, from what I've read. I wonder how many 'other' Deringers grace collections today?
