Project gun for this winter. 1903 (1918 serial number range, slightly over 800k), with a 4-30 4-groove barrel. The rear sight has been butchered, and I'm curious as to what I need to get it back to original. Got one picture of it before my camera died, so I hope it's enough to tell. Even in the shape it's in, I figured that it was hard to pass up for $150.
