I am here seeking help on a vintage radar detector. It's called "Long Range Super Snooper" i received it from my grandpa. I am trying to help him sell some of his belongings (he is almost 90 years old) so i was curious if this had any value. I was trying to look up info and see what people buy/sell these for but the most i was able to find was this picture:
If anyone had any info i was greatly appreciate the help!
