Don, I suspect they may not be very wet if they haven't been in contact with water or condensation. I bought a CVM-5 that had been in an outside shed that was hit by a tornado. It was rusted, there was a roof over it but hardly any walls left. Any driven rain would have gotten on it, and it was in high humidity.(Alabama) But since they are so rare, I bought it anyway.
Upon checking, it had about 1-2 megs to ground. If I'd needed in then, I'd probably tried it at that level. One meg. per 1,000 volts used to be the rule. But I put it in my basement Ham Shack in Alabama and it set there in the dry for about a year. I kept checking it and it steadly was going up. When I was ready to use it, for my HB 810's x 810's it read infinity! No heat, not anything but a dry heated and cooled basement! They should be checked with a megger though, It applies a DC voltage usually 500, or 1,000 volts. Most electricians, or any motor shop has these.
