First sold right away, but have another. These Kato fuses are though to find, designed by a Detroit Edison employee and only used here that I know of. There use to be a lot of these up, but only a few remain. These date roughly from the 1920's to 30's. A lot of the times the fuse stick is either missing or broken, this is intact. The insulators can be changed out too if wanted. I'll be at the National Friday and can deliver them, I can also ship if interested. Asking $70
