Marlin 1889 Lever gun chambered in 38-40 Winchester. This particular gun was manufactured in 1890.
The owner has had the rifle diagnosed as having a bad sear. Local gunsmith has not been able to find one and attempted to fabricate one without success.
He asked if I could recommend someone who has a lot of experience with them. I’ve got a couple ideas who to refer him to, but would appreciate if others with more experience with the old Marlins could give me any suggestions.
