I don't know that they actually had scanners back in the 50's did they? I think they only had radios. I have a similar type scanner with orange buttons for each channel and you just put in whatever frequency crystal you want for each channel. The scanner is from the early Eighties...
Ohhh, I'm a retard... I didn't read Creeker's post... but at least I was right :D We owned a Radio Shack in the Eighties so I had all the cool top notch technology :p
I am a Paladin, like the warriors of old, ready to stand on the line to keep others safe... A Sheep Dog, ready to protect the herd from advancing wolves!
