I got to examine a "no dash" model 60. The frame under the grips is badly rusted. Popping off the sideplate, there is is rust throughout the lockwork. That rust isn't too bad, as there was a bunch of jelled oil with flushed out with brake cleaner. The hammer was dehorned not expertly. The front sight was inlet for a plastic insert, which was gone. The screw for the cylinder release looks like someone tried to use a phillips screwdriver on it.
My inclination is to buy it (and I can get it cheap) then disassemble it. My feeling is that no matter what I do, I can't screw it up worse than it already is.
The sad thing was telling the owner who inherited that and other guns that there were several $500+ guns that were about two grades above scrap metal.
