Okay you ask how could I find this when I work in a shop. Well, a lady bought a few state quarters today and paid with this. http://i182.photobucket.com/albums/x275/clembo1872/scan0008-1.jpg Not great but worth $5 to me.
Trinary radar... and is there a term for a kind of up and down ladder too? (Well sort of... 13222231 has to be something besides just a radar, right? Well if not it's just a pretty cool radar.) Nice find! That's a keeper for sure.
