Here's a rare CD 155 unembossed insulator in a killer bright Yellow Olive Green! One small base flake otherwise mint! Measures 3 7/16" wide x 4 1/4" tall. Has unusual rounded dome and dimensions are smaller than typical CD 155. Manufacturer unknown. Found in South America and is not an unembossed Telecom (too small). Only one known, not listed in books or NIA website.

First email gets this beautiful Yellow Olive Green (almost citrine!) CD 155 for only $225 plus shipping. Thanks!
