That sounds right to me, Taigh.  It might be useful to remember that (with the exception of paratroop delivery and glider tow aircraft), general ash and trash haulers were not considered combat aircraft.  As a result, they were always further down the food chain with respect to new equipment.  Once the war industry started turning out equipment in prodigious numbers, then yes, they would have filtered down to the general C-47 population.  One clue to that was the AN/ARA-10, described below in a March 1945 release:

Pre and very early war aircraft were often 12-14 VDC and they used the BC-191 and BC-224 and often the SCR-183 for command. 

The early war C-47's through, as a guess, late 44/early 45 used the BC-375/BC-348 before they changed to the ART-13/BC-348.

For what it is worth, I haven't seen any documentation showing the ART-13 in B-24's.

The B-24 flight manuals I have, or have seen, all indicate the BC-375 and BC-348 as the liaison HF set.  C-47s had the ART-13 setup as did the B-29 and other late-in-the-war heavy aircraft.

I recall reading that when a radio in the C-47 that came to inspect the wreck failed they replaced it with one from the B-24 and it worked fine.  One article said the radio was an ARC-1, which I very much doubt.  I don't think that aircraft of that vintage, nor USAAF or USAF aircraft at any time had the ARC-1 installed. Maybe a SCR-522, or a BC-348 or one of the SCR-274-N sets would be possible.  Anyone ever read anything more accurate on this incident?
