Pivot hole examination of the plates
Three encircled holes on the front plate show minor wear to major wear
Same pivot holes on back plate show very minor wear, but will be re-bushed as the front plate, so all will be equal.
One of three pivot holes in front plate under microscopic view.
This one doesn't show as much wear, and is not as evident, but visible examination and turning in the light does show enough wear to warrant bushing.
My thoughts on bushing these holes would have been with some jewels, and would not be a problem, except for the higher cost. Second method would be to use bronze bushings, smooth broached, and burnishing of the pivots. I will check with the owner to see what he would like.
