I ran into a M1903 (30.06 of course!) that my dad bought years ago. It is one of the "low serial number" guns made before ww2 that has had some receiver failures. I don't know if it is safe to shoot or what the value would if we sold it, happy to answer any questions. The s/n is 243xxx and the rifle is in average to good condition for a 100 yr old mil surp. I can get pics if needed. Rock Island manufacturer.
