Description

#3717       Unmarked.       Dark green glass.

Height 3-1/4 inches.

This item has been in an insulator collection for decades, going back to the 1970's, and possibly as early as the 1960's.  Many years ago, some collectors speculated it might have been an insulator used in a similar fashion as the "Yandell," which was a very early sleeve type insulator used during the early portion of the threadless era.  It's also somewhat similar to the 1840's Cooke insulators from Great Britain, with a hole through the center for receiving and holding the line wire.

In more recent years, some collectors speculated it might be a form of sleeve for protecting insulator pins.  The overall shape and size is quite similar to numerous porcelain examples produced for that purpose. See third image showing a 1902 patent issued to Fred Locke for a sleeve designed to protect pins.

This example came from a pioneer New York State collection, and another collector found a similar example in a Central New York antique shop about 30 years ago.

The glass color and appearance is similar to some 1860's-1870's mineral water bottles produced in New York State, but it would be a stretch to attribute this mystery item to any specific glass house or time period.

An interesting characteristic about the two examples mentioned... both appear to have been formed by hand, since there are no mold lines.  Additionally, the area around the center hole opening at bottom has a scar all the way around, similar to a pontil scar found on hand formed glass (see base view in second photo).  After being fabricated on a punty rod, the glass was snapped off, leaving the scar.  This is further evidence of hand production, which lends itself to early manufacture.    

This mystery item remains in exceptional, undamaged condition.
