Mercury ribbed lightning rod ball

Description

Mercury ribbed lightning rod ball. Shipped with USPS Priority Mail.
Nice old ribbed/pleated large Mercury Lightning rod ball. I don’t know the maker but it does have the metal tube that runs through it. The usual chipping on the collars. Copper collars accommodate the large twisted rods. The Mercury is flaking as the pictures show. I do collect these however the Mercury type finish doesn’t appeal to me. Good luck bidders!
