An antique show find is this U-701 to the right, the first porcelain power insulator in the USA. Manufactured by General Electric and made of dry process porcelain around 1895. This is probably not from the Baltic-Taftville line in Connecticut built by the Ponemah Mills & Norwich Street Railway. More likely this came from the early Folsom to Sacramento line in California, a hydroelectric power line built by Sacramento Electric Light & Power Company.
