Unique Feature
This insulator is extra special due to the number 5 hand-embossed on the dome. This feature was typically added during the glass molding process and may indicate the mold or batch number, but exact reasons for individual numbers are not always known and add to the insulator’s artisanal appeal.
History
Hemingray No 40 was produced between 1910 and 1921, before being succeeded by the No 42 model. These insulators were made for telephone lines and represent a classic form of American utility glass. Each piece carries its own subtle distinctions, making every insulator unique.
Condition
This insulator is in very good vintage condition. There are no significant cracks or chips. Tiny air bubbles, minor nicks, or slight mold marks may be present, which are common for glass of this era and showcase its authentic heritage.
