Description

#2108       Unmarked.     Lefferts type rams horn.      Dark aqua.

Generally referred to as the "Lefferts hook" this early form of insulation was used on various lines.  Although most have surfaced in New England, they were used as far north as Nova Scotia Canada, and as far west as California. 

Various diameters and length of glass cylinders have been noted, this particular unit being larger in diameter than some. 

William Brooke of Jersey City, New Jersey received a patent in 1854 (see fifth image).  The patent was not for the insulator configuration, rather for a mold used in production of the insulators.

Chipping on one end of the glass (see second and third photos). Shallow, slice type chip on one side (from top to bottom) that starts as fingernail width and widens toward the other end.

Attractive dark aqua glass.

From the collection of the late Cecil Boos.
