The Russell iHorn is made from a vintage Russell Electric Company Signal Horn made in Danbury Connecticut. Russell Electric was an early 1900’s company. My best guess on this one is it was probably made between the 1920’s and 1940’s. Most of these signal horns were made in the 1940’s and were used in factory and other commercial settings to signal air raids, fires and other calamities. Simple, sturdy and alarming, the Russell iHorn will put you on notice.
