I have one in my 1951 (restored) M38. Back in the mid 60s, I was a new ham and a member of Army MARS. One day I came home to find multiple large crates in the back drive delivered from Ft. Sheridan; a complete GRC-9 station with power supplies, generator, radios, canvas bags, and antennas, packed for deck shipping. After several hours, I had the basic radio assembled in the basement, powered by 2 spare car batteries and the vibrator PS, and connected to our random length end fed antenna. Using the leg key, I made several CW contacts, the furthest being Wyoming from suburban Chicago. Much, much later I found the M38 and reacquired a GRC-9 system with the correct mount. Great fun!

Good job
As I learned, they were called angry 9 by the brits because they weren't so reliable on the field.
