Unfortunately, such a transmitter never flew in any Avenger.  The transmitter
shown is clearly an T-47A/ART-13 with O-17/ART-13A, used by the USAAF, not the
US Navy.  A USN unit should have been an ATC or an T-47/ART-13.  It's doubtful
that a LF/MF oscillator would have been used, but if it had been, it would have
been a six-band O-16/ART-13 or the ATC equivalent, not the three-band O-17 shown.

The transmitter shown also has no other associated radio equipment.  The
MT-283/ART-13 that should have been used to mount the transmitter is missing,
and the transmitter is apparently screwed on to some ersatz mounting rail.
The proper USN version of the transmitter would likely have used the early
MT-161/ART-13 rail or ATC equivalent, which was very different from the 
MT-283, and the MT-284/ART-13 on the bottom of this T-47A.

There's no LF/MF tank coil (associated with the O-16 or O-17), no receiver
(most likely the ARB), no trailing wire reel and control, etc. etc. etc.

This transmitter is just a "look good to the un-informed" prop that greatly
misrepresents any type of reality in the depiction of a historical radio
configuration.  It does more harm than were it missing.  It appears that the
aircraft owner's vast enthusiasm is countered by half-vast research. :-)
