Tiny - You gave me the VCCA link. I went there and was routed to AACA where I got the Klaxon info. Chevies used smaller klaxon horns as standard equipment until the late 20's. The larger, Brass Klaxons were aftermarket items. These horns were featured in a Band Piece / March written by Henry Fillmore in 1930 for the Cincinnatti Automobile show. It was called "The Klaxon - March of the Automobiles". The only other piece of music with a car horn in it (that I know of) would be "An American in Paris" - by Gershwin. Regards, BW
