I know a few are made in .410, perhaps bigger gauges also? ...just wondering if anyone has one and how it handles...Can't have too many lever guns!

Check out the Winchester 1887. Originals are available occasionally, but good reproductions are available from companies like Chiappa Firearms.

I just ordered a C I A pw 87 from copes distributing... less than $350 delivered... I ought to have it in a week or so...

This will give you some info.

My Father won a Winchester .410, but it's unfired. He's holding it thinking it may be worth something but I could ask him if he'd sell it.
