Those pieces on top of the magnet look very thin. I'm not sure what would do
that, but evidently something tore the ring up pretty good. Perhaps the other
pieces got through the gap into the combustion chamber and out the exhaust
valve?

Seems reasonable to me. I drove a lot of years with a pretty badly damaged
cylinder wall, and as you say it ran well enough. Oil consumption was
surprisingly minimal, too. I think my current TR3 engine blows more oil than
that old 3A engine did.
If I find time this weekend, I'll see if there are any usable 83mm pistons that
I haven't thrown out yet. Don't think I saved any rings, but a set of rings is
only $40-50.
