American Bulldog was a name used by at least two different manufacturers. Early guns by H&R date from the early 1900's, but Iver Johnson also marketed a revolver under that name in the 1970's. Johnson and Bye, a predecesor of Iver Johnson, also made an American Bulldog in the late 1800s. These can be identified by an owl's head on the grip.
