Crack in Winchester Receiver

[MountainScout]

I recently added a Winnie M1 Carbine to my milsurp collection of Garands and M14/M1A's. Having not been involved in the Carbine world, I had no idea what I was looking at but when a customer asked to trade for a AR10 lower, I jumped on it. After making the deal and getting the rifle home for a detail strip, I found a crack under the spring tube in the receiver which was very disappointing. It appears the crack had to be from improper manipulation or removal of the op rod at some point or maybe even dropping the rifle on the op rod handle ??? At any rate, this sure seems to be a weak point in the receiver and I'm wondering if this is common ? Anybody ever repair one of these cracks by weld / machining ?

Keep in mind this is not an all original Winnie so if I have to go with a new receiver, it wouldn't be the end of the world but if I have my carbine history correct, the only tube style receivers are the older winnies and rock ola's ???

Advice from all you Carbine guru's ??? Thanks from a FNG...

BTW, The receiver serial is 1036*** if it is needed or makes a difference.
