[Milsurplus] Seeking Info on RCA "AVR," "AVA" and "AVT" Items

[David Stinson]

Looking for photos and info on the RCA light aircraft series
radios with nomenclatures AVR (receivers), AVT (transmitters)
and AVA (accessories).  I already have info on:

AVA-120  AVR-7    AVT-15
AVA-126  AVR-15   AVT-23
AVA-127  AVR-20   AVT-110
         AVR-104  AVT-111
                  AVT-112
                  AVT-114

If you have information on any other pieces-
photos would be great but anything at all would be helpful,
I'd appreciate seeing it.

Thanks,
