What direction do you wish to go. Nothing looks like it needs restoring. If you want to get in to shooting it, there are appropriate loads you can get for a pinfire.
I once had a Boss gun that was built as a pinfire, but had been converted to centerfire. That would be a possibility.
Lots of us shoot these old guns but shooting a gun old as yours is sort of a personal decision. Any good gunsmith can measure your chambers and minimum barrel wall thickness to help you decide.
On the other hand that gun would look mighty good above the fireplace as well...Geo
