I too have all the requisite QSTs and will have a look (inasmuch as I
run a ATC). I think you'll find that the ART-13 was used in
considerably more than 4 aircraft, between the Navy, the AAF, the Brits,
and others. I can think of about 10 acft that commonly used either the
ART-13 or the Navy ATC. Regards de K3HVG

I am looking for a Collins radio advertisement that shows the four or five
aircraft the Collins ART-13 transmitter was used in.

The advertisement appeared in a 1945 or 1946 issue of QST.
If anyone can help I'd be grateful
Thanks
