Without a reproof, I'd worry a lot. [
I wouldn't. I'd just check the wall thickness and make a decision. I see no sense in worry.

Well . . . one reason to worry--given the fact that thanks to discussion boards like this one, people know a good bit more about proof rules than they used to--is that without a reproof, the gun is out of proof. Illegal to sell in the UK. And while you can sell it here in the US, you'll likely take a hit on value from anyone who knows much about British guns.
And having passed proof gives one a bit more confidence than simply measuring wall thickness. You know the gun has survived being fired with loads of far higher pressure than any you're going to use.
