My uncle recently gave me an old Iver Johnson 5-shot revolver that had belonged to my great grandmother. The only markings on it are a "626" on the bottom of the grip frame and "IVER JOHNSON'S ARMS & CYCLE WORKS. FITCHBURG MASS. U.S.A. PAT'D APR. 6. 86. FEB. 15. 87. MAY 10. 87. DEC. 26. 93. PAT'S PENDING".
The owls on the grip are facing the cylinder.
Any help in identifying manufacture date, black powder vs smokeless, etc. would be appreciated.
