These are in excellent used condition with no chips and ready to be used as bird feeders, candle holders, the start to a great light fixture, a paper weight (wrap wire around the top to make a photo clip), book ends or whatever else you can repurpose these for.

A little history about the

Armstrong TS Glass Insulator

Whitall Tatum entered the insulator manufacturing market in 1922, mass-producing insulators for use on power and communications lines across the country. Armstrong Cork Corporation purchased Whitall-Tatum in 1938, continuing insulator production under the Armstrong trademark. This Armstrong Straight Edge glass insulator was a basic part of the communications and power industry in the early 20th century and now serves as décor in our homes.
