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

If you can get a little closer to actual date, I can get you a copy of
the ad as I have all QST's from 40 to 49. I don't want to have to wade
through two years worth.
