Tom it looks like you have a "cool old gun" vs an "important and significant gun"
If you have faith in your woodwork and repair of that stock, and if the metal appears to be fit for a ride - I suggest you give the bores and nipples a good cleaning and run it
It has the look of a great 'user' with lots of character
I have absolute confidence in the repair. I was taught by a former Marine Ordnace Chief. The bores need some more love. You suggested the gun had been refinished. Curious as to why? As mentioned use some Ballital and 0000 to get the dirt off. Had to do very light 400 grit sanding to level the edges of the crack. A bit of had rubbing with some Truoil and best guess on color, I seemed to come up with a good repair, blended to the eye.
