This insulator is a bit different from the other purple WT's I have had. The skirt on this one is a lot shorter and rounded outward than the standard 154.Gorgeous coloured insulator that is a few tiny fleebites from mint. Photo taken in afternoon daylight. Comparing this purple next to any other 154 WT, the skirt on the purple is approximately 1/4" shorter/squatter than average thusly the entire insulator is 1/4" shorter than the standard purple WT or any other colour for that matter. If you would like a pic of them side by side for skirt/height comparison, please email me and I'll send one. Almost perfect condition purple that will glow when you backlight it or display it in a window. Upgrading from this one is going to be tuff. First mail to me... $35 delivered for this shorty WT insulator. I was not aware that the prices for purples had went down in the 07" PG, so have made a price adjustment.
