The most common carnival suspension is the 10 inch ball & socket disc shown here. Other much less common carnival suspensions include a 9 inch with hook and eye, a 6 inch disc with clevis fitting and a 6 inch bell with clevis fitting.

''These insulators are all sprayed with a tin oxide for the most part while they are still hot and going through an annealing oven so the range in colors can really vary. Finding the marigold ones with all the purple and pink tones on them is getting very rare. Of the large cable tops, some have no color on the skirt and real heavy color on the tops and especially around the wire groove area. The electrical leakage and arcing occurred where the tie wire left a v shaped empty air space between the tie wire and the electrical cable so it arced back and forth and they kept the leakage contained to a smaller area on the insulator with the metallic coating. It was meant to keep it from going from insulator to insulator or to phone lines. So they didn't care if the whole insulator was coated. It also can depend on the weather conditions of where the discs were kept. I'm sure salt air at the coastal areas wore them down more or sandy areas also wore off the coating.

They really are the most visible color on the poles but the depression time made all carnival or iridescent glass too expensive to produce. Hemingray stopped making it in the early to mid 30's and pyrex begain in the 40's through the 70's. The stamp marks on the big "sombreros" can be rarities, I think one of those is Dec. 7th 1941 and there is also I believe a Christmas one. " Carol Blakely
