#2283 CD 186.2 HEMINGRAY-19 Nearly colorless. "Hex nut."
A very unusual design with a brass, six sided nut molded inside the dome. A molded hole extends downward from the glass top, through the threaded nut, and into the pinhole which has a metal thimble.
Only limited numbers were found decades ago, and they have seldom surfaced for sale within the hobby during recent years.
A patent was issued to A.G. Steinmayer for the "spark gap" concept (see second photo). The 1943 patent illustration shows an insulator similar to a CD 186.1. Perhaps the CD 186.2 was designed just before or just after the CD 186.1.
This item is being priced the same as a previous sale of this type item ($625 plus buyer premium equals $700) to keep it fair and consistent.
Entire insulator remains in wonderful condition... very near mint+. Sparkling, shiny glass.
Stock photo. Actual item offered is nearly identical in appearance.
BUY-NOW option was removed once the reserve was met.
Lot is now an auction item.
Buy-Now and auction purchases will be invoiced vie email by mid day Monday, February 21. Invoices will also be viewable to purchasers on the auction site at that time by clicking the "MY ACCOUNT" tab on the upper portion of the auction page.
