can someone identify this underdash a/c housing?

There were several aftermarket "hang on knee knocker" units back then. The original owner of my 70 440-6 RR had installed one and I was forever grateful. MUCH easier to work around and deal with than the integrated OEM ones. "As a bonus" after I'd swapped in the 340 into the car later on, I also (later) managed to modify the mounting bracket and put the AC back in!!

I cannot quite pull up the brand name out of my mind, they were a "player" in the day, and likely soled them for such as JC, Sears, etc. I want to say "American Air" but not sure
