The Canadian Air Cadets have equipped some of their 2-33's with
transponders and they are real sticklers for doing everything
according to the regulations. Although the installation certification
they got would have been with Transport Canada it would probably be
useful to as a reference when you're trying for FAA approval.

The Air Force Academy 2-33s were also equipped with radios. Civil Air
Patrol has some of them now. Perhaps contact them? They were all
civil registered so would have needed FAA paperwork, one assumes.

As opposed to military aircraft, which are not usually certified, or
military pilots, who do not necessarily have certificates!

Good luck!
