oldfard,
I have to tell you that I was ready to suggest you hang this "old girl" on the wall and forget shooting it.
However, after viewing the images of some of the internal parts and their condition, I am willing to reconsider that thought.
The muzzle end of the bore is kind of rough as it is now, Could it be cleaned up some?
Setting one of these up to shoot could be a very expensive proposition.
Just to be able to shoot it a couple of time may simply not be an option for you?
I have not kept up with the current cost, But, this is the place to find that out.
My best,
Blair
