Rarity of Original Pre-WW1 Service Rifles

[Promo]

I'd be willing to bet a NRA Sales rifle, as well. Just for curiosity, is the raceway inside the chamber and the follower rib polished?

I now checked the rifle and since I anway took a few pictures of another piece from the collection, I thought why not of this M1903 aswell. Note the non-polished rails and the colour-hardened firing pin, cutoff and safety.
