I bought this from a vendor in Mt. Dora, Fl for about $10. It came with a CD 160 Hemingray with the dome sliced off and missing the upper screw portion. The split ring porcelain insulator is made by Thomas. The vendor was selling several items from the Central Maine Preservation Society (CMP) He said that the Society needed money and they were selling several hundred items.

The CMP Historical Committee Catalogue tag reads

2830 8-69 1000 #5 ITEM: "Insulators in wooden pin"
