I've got a Springfield 1903 that was rebuilt in 1944, it has a 1907 receiver. Two world wars and then the arsenal put it through it's paces so I feel comfortable shooting it. But that's MY rifle and the proof is in the markings and the work done to MY rifle. I cannot speak for your receiver or anyone else's. Like TheJoker said, it is ultimately your decision on what you do with it.
The paper TheJoker posted is awesome. I've had it book marked for sometime now and I have a copy of Hatcher's notebook (a must read). This paper and that book are two of the better pieces of information about low number rifles I have ever read. It definitely beats the uninformed internet know it all who says "All dem rifle be junk cause I heard it on them youtubez"
