Realistic TRC-101 Transceiver 23 Channel Walky Talky

A Realistic TRC-101 Transceiver made in the 1970s for Radio Shack (Tandy Corporation); it is a walky talky. It has 23 channels, a 49" antenna, ports for a phone and microphone, a port for an external antenna, a squelch dial and volume control. It takes 12 AA batteries and seems to be functional. I tested it as far as I could -it turns on, I can hear static on the different channels and the static is interrupted when I hold down the button to speak but I don't have another walky to fully test it with. Without the antenna it is just under 10 1/2" by 3 1/4" by 2 3/8 deep.
