That's a nice project.
Certainly a rifle that deserves it.

I stumbled onto an English built sporter on a M1903 Greek Military Mannlicher Schoenauer.
Steyr action dated 1906.
Luckily they nicely engraved onto the bbl "For 256 Gibbs Magnum Cartridge Only" or I would have had one tough time figuring that one out.
An Aldis Bros/Birmingham 'scope in detachable topmount on the rifle.
Well used but not abused. Perfect bore.
Sitting on a Gunshow table for $400 at OGCA last month.
Stuff like that keeps me still going to shows.

Good luck with the restoration.
Post some pics.
M/Schoenauers are a favorite of mine.
