Geez, Eightbore, if my comment was negative, what did you say about the Klunkermeister's back in the day?
One of the recent Vintagers had several model 21s decide to fail, all on the same weekend. Don't kill the messenger!
4140 is good steel, and, hard to solder. Not impossible.
I was thinking Max's question was a bit more rhetorical in nature, and not directed at me. The only other problem I know for fact related to the 21 is the single trigger and it's adjustment, which, isn't gunsmithing 101, so to speak.
Max, there are a few of us here that get shouted down anytime we offer up a less than starstruck opinion of the 21. Or, anything with the big red W on it. The lug is a bug-a-boo on the 21, and there exists documentation from John Olin that it was an issue with the gun.
You likely only need to get it fixed once. But, I'm just guessing you are going to be joining us in the shouted down camp.
Welcome.
Best,
Ted
