Very sweet rifle. I bet it wasn't carried much due to the nice blueing left on the floor plate. Not sure on the muzzle blueing wear which occurs from hands gripping it while the butt is on the ground. Typically you would see patina there too. The follower shows very little evidence of cartridges being chambered so I bet the bore is like new. I bet it would push over 2k on broker.
Somebody had the stock off at one time because of the duff cut. That's likely the reason the band spring is missing.
