Interesting 1941 Winchester

[peter100]

I also have a WRA from 11/44 with the same hole. I find it hard to believe that with some many receivers looking like that, that no one noticed, or worse yet, the parts inspector saw it and passed it, without knowing for sure if would fail during a battle. I think that since they seem to affect both SA and WRA, that somebody, somewhere must have said that the defect was OK and passed them. Since they all occurred at the same place on the receiver they must have know that the potential existed for that to happen. I guess the only way to solve it is to find the acceptance standards for the receiver.
