Insulator on right is a W.Brookfield with no SN on top. Has thick skirt wall and shape of dome is different the insulator on left. It measures 3 1/4 inches across the base and is 3 3/4 inches high.
Dark insulator on left has Brookfield on front skirt on front skirt and SN10 at the top of dome. It measures 3 1/8 across base and is also only 3 3/4 inches high.
I know the left insulator is a CD 162. Not sure about insulator on the right. It at least has the base measurement right according to price guide. No other measurements I mentioned above match PG.
I've been in the hobby for a very long time know and I'm pretty sure I've run across the same problem early on so this is kinda embarassing to have to ask. Sure wish there was a more accurate way to ID these just using my many prices guides.
As of now I'm only had two responses to my questions. They both agree the insulator on left is a CD 162 and the insulator on the right is a CD 162.3. Only Star 162.3 seem to measure the full four inches in hieght that the PG indicates.
