I would be VERY tempted to use it.
No problem with the barrel walls being too thin. They are about 1/2" thick.
I'll have to bring a light tonight to see what the bores look like.

Might be worthwhile to pick up if no-one else takes notice of it and it goes REAL cheap. That could happen in this place.
Unfortunately I couldn't afford to keep it, so it would just visit for a while until I found a it new home far away from the People's Republik of New Joisy.

We'll see what happens.
