[Collins] Module identification

[Glenn Little WB4UIV]

Does anyone have information on Modulator and VCO 793-9307-001 and 
TCXO-Multiplier 793-9314-001?
These are plugin modules that look like they would plug into a card cage.
Date codes indicate late 1970 or early 1971.
The Modulator and VCO has a low pass filter 673-0015-010.


Thanks
