In early July 2020, Wyatt Johnson requested information on all glass Westinghouse insulators. I have a CD 102 Westinghouse No. 3 (no mold mark) in a color I call very light yellow -olive-green. I purchased small collection of insulators about 25 or 30 years ago that contained this insulator. My understanding was that this Westinghouse was collected in Upper Darby, PA which is west of Philadelphia, PA. The picture was taken in cool white fluorescent light and is very close to it's true color. The glass in the insulator skirt has many open internal bubbles primarily in the threads.
