Handheld military radios - $50 (Dallas OR)

3 AN/PRT-4A transmitters and one AN/PRR-9 helmet receiver These are Vietnam-era field radios.
They need batteries and some TLC.
I have no idea if they work or not.
They're apparently a collector's item for radio enthusiasts.
Some parts may be available for them.
More information on them is available here: https://prc68.
