I think these guys look like little Buddhas. I managed to find the 4th Buddha [Westinghouse-far right] in my collection on Vi Brown's table last Saturday at the Merritt Insulator show. Years ago, I found the first one, the CGE unit [Canadian General Electric] in the bush along the CNR tracks near Alexandria Bridge, north of Hope in British Columbia. Russ Paton gave me the Muloney unit at a Fort Langley insulator show, and I found the other Westinghouse unit at a Mission Antique shop. These are a type of fuse, and there is an insert [knife] which is placed into the bottom to complete the circuit. I would be interested in hearing from anyone that has a similar but different unit available for sale. Thanks for looking.
