Within a couple weeks time towards the end of 2014 my 210 SN18 collection grew from 1 to 4 insulators all in different colors. The only one I had before winning a questionable green on eBay (far left) is the light aqua maybe ice blue piece on the far right. Next came the blue aqua piece which I found at a friends antique shop nearby me. At the time of purchase I had no idea it was different then the only one I had. The last and most interesting insulator second from left was shipped in a box of insulators from a California collector that was thinning out his collection and selling 40-50 insulators for $10 a pop. Before it arrived all I knew or more closely guessed was that it to was a #18 but the appeared to be a light colored green in the other collectors pics and different from the eBay insulator I expected would be on my doorstep any day.
