That's my idea of the perfect fix, I've seen receivers, of course not when you are looking for them, but I think that's the way I'll go. It will repair and potential rust damage- assuming it's
better that this one which is not difficult to find....and hopefully eliminate the serial number issue. I really like the barrel, it's too good to throw out, but the receiver is too big a question mark... That seems like a reasonable way to go. I think it's a good rifle, aside from the obvious.
