Here's a rare porcelain battery rest insulator set from France. Unmarked. Comes in a size previously unknown (to me)- measures 4 15/16" wide on upper rim x 1 1/2" tall on base piece; 3 1/2" wide on upper rim x 1 3/16" tall on smaller top piece. Base is mint condition and top piece has pinky nail flake, otherwise excellent shape.

First email gets this rare set of French porcelain battery rests for only $250 plus shipping. Only one known at this time. Thanks!
