[Milsurplus] Radio Operators ARR-41

[Smith]

The response to my original background query on the ARR-41/R-648 has been
fair and leans toward the USN as sole user of the ARR-41
I would still like to obtain the URL of any Aircraft Radio Operators
Associations. They must exist somewhere, but my searches have not yielded
anything. I am still trying to confirm the possible existence of the ARR-41
on USAF aircraft either tactical or mission support.

Thanks
