Not bad guns. For anyone owning one, do not try to remove the grips. They are supposed to come off by prying up in the middle rear and sliding backward, but the hard rubber is old and almost always breaks. Takedown is neat.
FWIW, I did take the grips off mine for it's initial cleaning. They all get that, prior to getting checked into the collection hotel, aka the safe. I can see what you mean that they might break, I was pretty careful not to kill them, but it's certainly possible to screw up. The gun really isn't rusty, but something made a red cast to this particular photo, I'll have to reshoot it someday...
