	As far as the first device is concerned, the "pinchoff tube" at the
right side of the center part indicates that it is some sort of vacuum
device, and was sealed when the tube was taken off the pumps..  Looks to
me as if it is a disk seal triode or tetrode, but can't tell from the
picture which parts are metallic and which are insulating.

	Is the second photo the top view of the same device?  Sort of looks
like it, but then where are the cooling fins?
