Item: 47  Description: U-1735 No Marking w/ Green Dome. The provenance of this insulator could not be better! Our consignor in Germany says the insulator dates back to the 1915-1920 era in the city of Donauwoerth, Bavaria. View 3 and View 4 show this insulator on the side of a house before it was taken down. The address of the home is on a label inside the skirt of the insulator. Our consignor says the green heads (domes) were used to mark the three phases of the 127/220 volt AC grid, while insulators with all-white glaze marked the neutral wire. That methodology ended after a short time. He said not to confuse green heads with U-1735’s that have a green stripe on the skirt, indicating those are much more common and some are still in use today on railroads. This insulator is believed to have been made at Porzellanfabrik Hermsdorf in Kahla, Thuringia as at least one was marked with that company’s logo.  Grade A-Minus with only minor wear.
