Here's a pair of clean and shiny Brookfield signals with amber in them. The one on the left has amber wisps throughout which was hard to capture in the photo. It also has small pot stones here and there and lots of tiny bubbles giving it a fizzy appearance. Very tiny ISC is all I can find wrong. The one on the right has pronounced amber swirling and is maybe a tick or two from mint. These both have a backward "7" on the dome in the exact same position although the wire groove and upper ridge profiles are slightly different. Mold rework maybe? $15 + shipping for the pair. Thanks for looking. How about $12 for the pair?
