I have a cople original Argo as used by Yellowcab a few years ago. These work great when wired in correctly.$20 for 1 and $25 for the other. Next,I have a classic Rockwell-used everywhere but especially east coast like New York. This is the old mechanical type with flag. Very cool-$45. Finally, I have a Viking-not the greatest shape but only twenty bucks.Or, buy all four for 75 bucks! call Listing originally posted at http
