Here's a really cool miniature porcelain suspension insulator found in Germany that advertises in gold plate lettering a copper power cable manufacturer M. Brown & Broveri & Cie. I've never seen another one go-with like this by any manufacturer. Insulator and cable display are in great shape with some base rubbing on the insulator but displays great.

First email gets this unusual item for only $150 plus postage for this cool collectible go-with. Optional insurance extra.
