Ok so i think i know what it is used for. It has 20 small electro magnets on the back. When the current hit the copper coil it will pull the pin down releasing the arrow so that it points to the corresponding number. Along with the arrow the bell will ring to notify who ever. That is were i am lost. Is this for a hotel, hospital, upscale restaurant? The only information i can find is ( on the top) "The Knapp" (On the bottom) "Montana electric co." This item was found in Butte Montana. Any help would be appreciated.
