This original casting Nathan P5 salvaged from Rock Island GP7 number 1265 was the first air horn in my collection. I purchased it from a friend who bought it from the scrapper at the time of the 1265’s demise. It is set up in the typical Rock Island configuration of the odd number bells 1, 3, and 5 facing forward and the even number bells 2 and 4 facing backwards.
