Here's an unusual ribbed porcelain fuse insulator found in Australia and made in Japan. Threaded for a pin to attach to power pole like the Essantee Fuse insulators. Cap for fuses is missing. One teeny tic mark shy of mint condition! Has cool copper brown color.

First email gets this Unlisted in the books and NIA website very unusual ribbed porcelain fuse insulator for only $50 plus 8.40 shipping. Thanks
