5 tone Casey Jones style steam whistle made from old boiler tubes. For Sale

Up for sale is a 5 chime Casey Jones style whistle shop made from old boiler tubes. I have blown it off air at 125 and it sounds really good. Inlet is 1.5\". Bowl is brass. Many of the old steam engineers had their own whistles made in the locomotive shops as there was a never ending supply of old boiler tube laying around. If they changed engines or changed runs they frequently took their whistles with them as as the whistle was their signature. I am not sure there was any science to building these whistles as much as trial and error. I will build a wooden crate and ship ups at a flat rate of $50 in the US.
