Gunyooper,
That was a fine purchase for sure!
The gun has certainly seen better days, but, it's all there more or less, minus the trigger guard. I would say it needs more of a stabilization, than a restoration.
The area between the barrel, tang and lock needs the most attention. It's difficult from the pictures to see if anything is actually broken, or just rusted, eroded, maybe bent a bit. None the less, all that can be put back into reasonably good condition, and would strengthen that area of the rifle as well.
A trigger guard, a ramrod, replacing a few missing splinters of wood and a couple other things here and there, and it'll be a fine looking rifle again!
It looks like you have the lock area supported with twine which will help to keep things together, and with the heavy barrel, care is really really necessary!
Besides the name on the barrel can you read the inscription on the cheek piece inlay?
