CB&Q diesel horns

[Ed Pavlovic <epav1@w...>]

Was wondering if anyone on the list might know the
manufacturer and model of the two chime airhorns used on the
CB&Q's diesel locomotives. Some of these replaced the
original single chimes on the first generation units, and
factory installed on most of the later engines (GP30 and
up).

Thanks in advance,
