As long as the barrel is tight and the chamber in the barrel is not cracked or bulged personally I would have no concern. Not only is the pressure low but the case is small. But JMHO

I live in southeast MO so humidity in the 80's is a daily occurrence (even in the winter), plus it's at least 70 years old, so this may be what caused the problem. I'm going to try to clean off as much rust as I can when I have a few free hours.

I think that's a good idea Nasaboy87. I can't help but see a line of "demarcation" or boundary/separation shown in your picture, which I believe was caused from moisture. That line has some length to it. It sure does look nastiest at the receiver/barrel junction. There are salts involved in the bluing process and maybe these get released and intensify corrosion during the corrosion process. No expert, but bluing breakdown isn't a nice thing. Sorry not preaching to you at all, things happen to us at times beyond our control.

There is a product that is supposed to remove rust without damaging any remaining bluing called "Big 45" it looks like a copper dish cleaning pad but it is supposed to be different than those. It's supposed to basically have tiny razor sharp edges that slice rust off leaving the harder bluing unharmed.

Good luck. I certainly hope it is corrosion as that wouldn't be as serious as a crack. Again, could be corrosion because I see that "Line" in the picture that extends thru to the end at barrel/receiver. The barrel/receiver junction is probably where the moisture met more air. Moisture + oxygen = greater degradation.

P.S. Those tiny white areas in the photo could be salts caught in depressions...the worst thing. I could be wrong but when I see white like that it says salt to me. That is unless we know it is otherwise...for instance left over "dry wax".
