Picked this up today at a local collectible show. For a CD 128 Pyrex in carnival it is unlisted. Mark Lauckner posted one he found on October 1 2016.This insulator has been used in its carnival state. Wear marks show it. The seller who sold it said it came off a line that ran east from the San Diego, CA. area out to the desert towards the Sultan Sea. Does anyone have any information on such a line? Regards, Dave
