Bob-

I'd say forget about orig anything with that rifle.
Go with what cool classic round you've ever wanted and run from there -- or something like that.

Maybe start with the boltface and see what other cartridges share it (lots of choices there) and choose from that list.

Want a cool 9.3/something?
How about a hot 7mm?
I like my 458WM
Wildcats appeal to you?

Really, there doesn't seem to be much there to go with on a 'full restoration' of any sort and I see a good canvas to start with on a new 'Bob's favorite field gun' project.

Keep it low budget, set it up with a round that's got the right kind of 'damn that's cool' for you, and run the hell out of it.
If that stock is salvageable have your smith put a cartridge trap in the underside or buttplate of the stock, or some other feature you've 'always wanted' in a cool old bolt rifle. Keep it cheap and keep it fun.
