Action retains approx 70% orig case hardening color with loss due to normal hand wear. Top lever, floorplate and trigger guard retain a considerable amount of their orig blue. Stocks retain over 90% of their orig hand rubbed oil finish, grain open, and rather dry. Checkering is slightly worn and soiled. As this gun was made for Henry S. Morgan, Jr. when he was about 12 years old, a lengthening piece was added later, workmanship was not of the highest order. Bores are excellent, bright and shiny throughout. Action is tight. Bbls are on face. Ejectors are very slightly out of time. 52928-1 MGM (5,000-7,000) C&R – Lot 3164
