I didn't want to step all over the "putting a DR back on face" thread so I started this one.

A touch of background...

A good customer has brought me a 1890's Remington hammer double in 10 gage. Its been cut down for shooting Cowboy action. While the barrels still lock up tight they are "on the flats" and the top lever has used all of its stroke. Basically its time for tigtening before it goes "off face" and eats itself alive. I typically work on lever guns and revolvers, so this is new to me.

Here's the meat.
As its not an overly valuable piece, the expence of replacing the hinge pin, honeing out the hole, making a new pin and all that entails along with refaceing the hooks is a bit steep for the desired results (a funtional Cowboy gun). My intention is to soft solder a shim in the face of the hooks and go from there. What else should I be looking at as I go? I understand I'll need to black down the barrels to .003-.006 above the flats and I have no issues with that aspect, but is there something else that could to bite me in the butt here?
BTW it has a dolls head, what do I do with this feature, anything, nothing?

Thanks
