The Collage made a reproduction of the pin to mount the insulator on for this display . The ring is original but has been sand blasted and hot dip galvanized to restore it's finish as it was found in a swamp and was rather rusty. Please see the next two pictures in this category for close up's of the display packs. Use the search function and type in " M-3890" for numerous photos of this very historic insulator design ...both vintage and modern.
