Oh Man, M 1 Restoration huh, Well now thats a tricky subject. If that rifle is all original as it came from the arsenal, its worth more that, way no matter the condition, I myself would just try to find one in better condition.
Remember, that piece of machinery went thru the war, it has history. If its nothing special you could send it off. Fulton Armory does a good job but it aint cheap. I collect them, and one that has been restored does not mean much to me. any restoration wont keep it original. You could find someone to restore it to original configuration but thats even more money.
