You have a very nice deer rifle there, looks like it should shoot well for another century. The action is slick and fast, it's light weight when cut down like it has been, and the cartridge is just fine for deer or black bear, even elk, out to 200 yards. Don't bother to scope it, if you need long range capability, get a modern cartridge and scope combination.
Value ? $200-$300, but for that kind of money, I'd keep it forever. Don't bother with a new stock unless you want another hunting stock on it. You'll need new stock, barrel, bands, sights, etc., etc., if you want to restore it to military condition, and it won't be worth what the parts cost, let alone the gunsmith labor to do it.
