I'd like to find a post mill action with the early threads, so they would match.

I had one post mil receiver with the early threads but darned if I remember now what it was. 250 I think. I did talk about it here when this subject came up before. Can't remember why I had the barrel off it either.
That's what's great about getting old, you can have all these cool stories and no one expects you to remember the details.

"Really, what did you do?"
"I don't remember"
LOL
