Here's a rarely seen and very cool looking two-piece porcelain insulator from Germany. For more details and additional photo [click here]. Raised embossing internally: 25A 500V 930.E2 2 (backwards) in a circle. Incuse marked with "M" with an "I" above it surrounded by symbol of a house [click here]. Logo is similar to Berghaus A.G. but not confirmed. Marking is found on the side of the insulator and again on the top of the bottom piece. These were used on overhead streetlights at railway stations.

VNM with only light nibbling on internal umbrella threads. First email gets it for only $150 plus shipping. Please notice my new email (above) for PayPal/communications. Thanks
