Bought an 1877 S&W Schofield revolver at a gun show last year. Was complete sans front sight as is usual with the cut off barrel versions found. Had been nickel plated some time in the past. Other than some poor prep work maintaining corners and such it is OK and still in good shape. Rebuilt the projections that hold the cylinder in when the revolver is opened and made new screws for the top latch. Had the cylinder locking bolt and firing pin on the hammer rebuilt as neither could do the job they were designed to do. Got it back from the local gunsmith, who works at levels the big name pros do, and it is nothing short of amazing! Every chamber indexes and locks up solid, no end shake, and the firing pin/hammer looks like it was never messed with. Have not decided what to do for a front sight but an 1877 dime would be the cat's meow, correct vintage and not an uncommon fix in those days.
Will post some pics when I get home.
