#2105 1016 Unmarked. "Cylindrical block." Aqua.
Nearly three inches in length. An early "block type" insulator which was first discovered in 1994. Two examples were found, along with a group of 737.6 threadless (Lot #2116), contained in a wooden box that rested for decades in the attic of a circa 1840's-1850's building. The building was located in a northwestern Pennsylvania town, which was on the route of an ancient telegraph line between Erie and Pittsburgh, Pennsylvania.
This type insulator was likely produced in the 1840's or 1850's, representing a very early form of insulation. It has features of both the rectangular (squared) type glass block as represented in Lots 2102-2104 and the "Yandell type" in Lot #2106. The deep, semicircular slot across the top center facilitated a wooden dowel which locked the glass cylindrical insulator within a crossarm.
This particular insulator probably never saw usage, as there's a thin glass fin still intact within the wire slot, which probably would have been broken loose if a wire had been inserted.
Chip on the inside of one end, and an associated shallow, narrow flake on the exterior. Pretty nice condition for this thin, fragile design.
Considering the rarity of this type insulator, it may be decades before another becomes available, if ever in a lifetime.
From the collection of the late Cecil Boos.
Update, 8:10 P.M. Saturday, January 29. Third photo added. Horizontal arrow points to the chip on inside of the insulators end opening. Vertical arrow points to the outline of the shallow flake on the exterior, which shows through the transparent glass, enabling us to see it in this photo.
