That Navy is a beauty! It looks like it has had an interesting life.
Aging those flat finish revolvers is sorta tricky, I worked over a .22 Cimaron Plinkster. I used buffing compound and a 6" wheel. It came out shiney bur worn-thru in places and it really faked authentic wear. Too bad the revolver ntotally broke at 1500 shots and is now a Bookend.
