Two of them, new, and still in their original very-aged packing crates. (1 shown)
The only identification on the box, is... "ADM Part. W5244 Valve Circuit-C"

	End view of the long bottom-section tubing with the filament wires making their entry. The Cathode threaded fitting is on this lower section, (out of view) and electrically bonded to this lower portion of the tube, which is from the flange downwards. Connections to the actual valve itself, are all hard-wired and soldered at the base of the glass valve.
	The top of the main body contains the valve within a small region inside the metal flange. The top electrode for the Anode, is screwed into the top section of the tubing, which is insulated from the other sections at the flange A note in the box tells of the var. capacitance adjustable here..
	Dis-assembled view, showing the mica insulator, and the hard- wired base of the valve itself, which is labeled as a CV-16 valve. The central cooling fin of the valve is joined to a wire at the flange, which is the Grid.

(There are a couple more photos to come, of some other parts, soon).
