The following series of posts outline detail on three CD 133.4 Wormser Style insulators (green, sky blue and SCA) which came from Southwestern Pennsylvania. The third post is on a SCA /amethyst CD 133.4 which was purchased from a Ray Klingensmith insulator catalog in the 1990's. Specific details on this CD 133.4 are as follows:

CD-133.4 No Embossing (Wormser Style) - 3 Piece Mold - Crude Medium Amethyst - Measurements - 70mm Wide x 97 mm High - Found In Southwestern, Pennsylvania - Likely Made By the Wormser Glass Company.

This insulator has amazing character with large and small bubbles, pot stones and milk streaks. This has to be one of my most favorite insulators in my telegraph insulator collection.
