Description

#718     CD 199       Emerald-prism.      Blue.

The emerald was a trademark of C.S. Knowles Company.  Insulators produced for them often included a large prism.  Additionally many of their saddle groove designs also included a large embossed 1890 patent date.

A sizable transposition type insulator which was very prone to damage, especially the wide umbrella at top.

This one fared much better than most.  Has a shallow, 3/4" base bruise (see photo) and a pencil eraser diameter nick, next to a small open bubble on the underside of the umbrella.
