Here is a new acquisition. A white porcelain SURGE insulator with it's mounting bracket. The insulator itself measures 1 1/2 inches tall and 1 1/4 inches diameter at the top. There are 8 drip points (firing rests) equally spaced around the base. "SURGE" is embossed across the top with "TRADE MARK REG: curved above and "PATENTS PEND" curved below following the outer edge of the circular top. The edge embossing is very small and faint but readable..
