Description

#1717       CD 125      PAT APP FOR      W. U. 5      Slightly opaque blue aqua.

This is one of several insulator styles produced during the 1880's using a pinhole threading method patented on August 14 1883.  Possibly produced by a glasshouse in Ellenville, N.Y.

Note this example marked with "W.U." rather than just a "5 over a letter."

The embossed "5" on reverse skirt is large and an attractive fancy script style. 

Very near mint.
