This is a great item for a truck. Sounds great! This will turn heads and get smiles! Not as blaring as an air horn. Your buddies will hear you coming and know it is you!

According to the 5 chime consultants,
Hancock is perhaps best known for their steam whistles, such as the \"steamboat\" whistles on Union Pacific 844 and 3985, SP 4449, Frisco 1522, and N&W 611. The Hancock type 4700 was an air whistle intended for use on diesel locomotives that simulated, as much as possible, the sound of a steam whistle. The whistles were used extensively by New Haven, Seaboard, and Minneapolis Northfield & Southern, as well as a number of shortlines.
The whistle could be ordered with or without the bowl-shaped reflector. Without a reflector, the whistle wascatalogedas a type 4710.
Original tuning was: A major triad (E, A, C#)
Though pleasant to hear, the 4700 was not as loud and commanding as most airhorns. Difficult to hear at speed, the whistle eventually fell out of favor, and production ceased about the middle of the 1960\'s. The last large user was the Minneapolis Northfield & Southern, and with their merger into the Soo Line, the whistles were soon removed. Some Hancock 4700\'s can still be heard on shortline and industrial locomotives.
Overall size is 17 3/16 wide, 18 inches deep, and 11 inches tall. The whistle is 4 1/8 inches in diameter. The inlet is a 3/4 inch diameter threaded hole corresponding to 1/2 inch pipe thread NPT.

Total weight of the whistle with the aluminum cowling is 31 pounds.
