My husband and I have been looking everywhere for info on this gun. We have inherited quite a collection of guns and are trying to figure out what we have. The top is marked "MERWIN HULBERT & CO. NEW YORK U.S.A. PAT. APR.17.77 JUNE 15.80 MARCH 14.82 JAN .83" The grips are mother of pearl- one side carved with Mexican eagle.
Any help would be greatly appreciated
