The Grover

The Grover iHorn is made from a Grover Products Co. air horn.  Grover Products was founded in 1937.  The exact age of the horn cannot be determined.  The Grover  is used on trains, trucks and boats.  Mid-sized but mighty.  Well worn but time tested.  The Grover is the master of both amplitude and quality.  It is a functional piece which signals its intentions.
