Here's a scarce mid to late 19th century glass battery (accumulator) rest insulator pair made by Kilner Brothers, Ltd in England. This was uncovered in an old trash dump years ago. The larger top piece is aqua and uniquely micro bubble packed! (Bubbles stand out when underlit!) I have not heard of other examples with this feature! Have you ever seen another bubble packed battery rest?? The top is T40. (see glass ian website for details on his numbering system)

The smaller base piece is Green with some factory pot stones. This was the only Green one found by me. This is B30.

A small base flake about the size of 2 match heads. Both pieces are very crude and have the original pontil marks on them indicating they were blown into a mold. Easily VNM!

First email gets this cool pair of tough battery rest insulators for the great price of only $135 shipped. Thanks!
