Thought I would post a pic of the 100 I just refinished. Don't look too close! I use rattle cans for paint. Still, a very satisfying hobby. This one has new rings but mostly all original parts (as far as I can tell).
Bfleish, I'm afraid to use any kind of solvent for fear of damaging insulation. Still, it's a mess inside and I'd like to swab it out. I don't think the S/G has ever been rebuilt. The fields look to be in good shape.
