Re: US Revolver Co.
The book on Iver Johnson is "Iver Johnson ' Arms and Cycle Works Firearms 1871 to 1993 ' by WE Goforth ". There is a book on H&R's in the works but it has not been published as of yet. I know of no dedicated websites that has the information that you are seeking other that sites such as this with contributors who have the book. If you use the search feature of this forum you will come up with a wealth of information on the U.S. revolvers.
