Hi Don, I received your response which is below. Maybe the failure to

They had been stored in an old house, where termites undermined the floor, which then fell onto the ground and rotted. The tubes had been in their original cardboard boxes that had rotted along with the wood. Back in the mid 1980s the owner was in a nursing home and his wife called me and a friend and let us know we were welcome to come up and haul anything home we wanted, since her husband was terminal and the local ham club yokels had advised her to haul all the stash of old radio components and tubes to the dump because "nobody would be interested in that ald stuff any more", but fortunately she called us first because she wanted to see it go to a good home, not the landfill. While searching through the rubble in the old house, I happened to discover a buried tube, and kept digging and found a half dozen 211s and some other t

Back in the mid 80s, hams from the 1920s and 30s were dropping like flies, like WWII vets to-day. I just wish I had had the wherewithal back then to have travelled over the country and rescue a lot more of that stuff from the garbage man.
