There's a lot going on in this CD 134 K. C. G. W. FAIRMOUNT. A dome that is filled with bubbles and internal stress lines. The color is a greenish aqua. There is a wire groove chip right of the embossing (you can spot it in the photo) and a nibble on the wire groove ridge at the left side mold line. Asking $40.00 plus actual shipping cost for this very active insulator. Check, money order or PayPal.
