Barrel appears to be walking out?

Thanks, everyone. So it seems I was on the right track by assuming it was some weird unknown barrel that was pressed in. At least I don't feel stupid for not being able to recognize an aftermarket barrel from some catalog back in the day.

I have a mini mill and a press, so I almost want to drill out the pin and press the barrel out myself to satisfy my own curiosity, but I also don't want to bugger up any remaining threads for you.

I just measured the barrel shank and it's measuring 0.6765" or 17.17mm (at least according to my crappy Harbor Freight digital calipers). So maybe there's still threads in the receiver? Fingers crossed.

As far as safety issues, I got lucky. I didn't get any bulged or burst cases, but no way am I planning to try and shoot it as-is.
