CD 133.2 P. & W. Aqua |
|
Perhaps a product of the Beaver Falls
Glass Company of Pennsylvania,
the CD 133.2 P&W is among the
earliest of threaded insulators made.
In fact, some CD133.2 insulators
appear to have been pressed in the same
molds that originally produced
CD 728.2 theadless pieces.
The addition of threads is noted by
bold embossing on the skirt which reads: L. A. C. PATD JULY 25TH 1865 P & W The letters L.A.C. refer to the inventor of the threaded pinhole for glass insulators, Louis A. Cauvet. This example was found in February 2001 along one of the oldest railroads in Mississippi. After 120+ years "in the wild" it is still in VNM condition. |
