   I'm trying to identify the airhorn the UP used on the old GP35's ... I understand this was one of the first attempts to mount the horn behind the cab. But I'm not certain what horn was used... a K3?
   
   Any help or additional knowledge here would be greatly appreciated.
   
   Thanx

   "UP used to have the Leslie S-3L on everything, but in recent years they have been buying the Nathan (AirChime) K-3HA."

   That's about the best I can find.
