Very Early Inland. Possibly Unaltered

[INLAND44]

I'm afraid I have to disagree with you on the finish. The finish matches my other carbine, and every other carbine I've ever handled.

A quick google image search als shows a somewhat "gloss" like finish and not the flat that you indicate.

***edit****

I'm also taking these pictures right under an overhead light so might be getting some excess shine due to that reflection.

Seeing a bunch of carbines in the wrong configuration does not make my statements wrong. Avail yourself of the M1 Carbine manuals and read it for yourself. But anyone should be able to understand that you don't have a glossy finish on a military weapon. At least not by design.
