These were among the last things pulled out from the estate junkpile. Stuff they wanted to scrap, believing it to be worth big dollars. In reality, it would go across the scales in one lot for 2 cents a pound.
"continuous rotating potentiometers" I guess may have been for a servo unit or something. Anyone know what these are useful for?
typical unit is about 2.5" diameter, 1" thick, 1/4" shaft.
ELECTRO-MEC
TYPE D62 30cz-G1
160 deg CCW-TER 1=78.97%V (huh?)
terminals 1-2 250K->0
terminals 2-3 0-250K
other one 25K same action.

and a few more of them.

DAVEN attenuators
look like 'pads' with "IN", "C", and "OUT" terminals. Have detents corresponding to large sets of contacts. These may be the good stuff.
WE-137-3 -nearly 360 deg from 0 to max
WE-138-3 -about 60 degrees from 0 to max

Apparently a RTTY transmitter and receiver, intended as a test generator and test receiver. Each has a CRT with a scale around the edge, whereas a teletype need only 0 and 90 degrees marks. The first thing I thought was that it might be a constellation display. I don't know what they really are in modern parlance. TDMS though, in the 1960s. Should have images later.
RADIATION INCORPORATED TDMS-5EB-R.1 TRANSMITTER
RADIATION INCORPORATED TDMS-6EB-R.2B RECEIVER
They are fascinating anyway.
items shown @ 4:07 on right hand side of girl - center and left units have same graticule on CRTs. Rack says "TELEGRAPH MONITOR"

JERROLD CM-6C MARKER GENERATOR
several switches presumably for crystals. 2-100MHz.

LTV G-166H RECEIVER
"spook receiver" 250-1000Mhz AM and FM - two tuners and one I.F. seems rare enough. The guy was in charge os a lot of repeaters and transmitters and links, so that explains also the Nems-Clarke stuff found earlier.

a couple hundred pounds of transformers and chokes. LOL need to go through them.
