About a month ago I posted a message requesting information on the company who
manufactures LESLIE airhorns. While I got a few answers none led to the company
itself. Well not being the type to give up I just kept on plugging away at it and
this is what I came up with.

Leslie Controls a Division of Watts Industries.
12501 Telecom Drive Tampa, FL 33637-0906
