1. Rockville Receiver (frequency = 486 MHz) - no issues, in good shape, in original box,
2. Three VHF microphones (NOT from the Receiver Set, different frequencies!),
3. Take those two more microphones on the last photo if you can animate/reanimate them.
Receiver and VHF microphones are in working condition, but you have to be sure that you are buying what you need!
All that can be useful for the engineer/musician/specialist who already has similar devices and needs a backup or extension.
