Two tone horn

[Hemersam]

Speaking of air horns, when I was 16 yoa (1951) and growing up in small-town Oklahoma, I put a couple on my '49 Chevy (torpedo-back) and was having a great time until one of my Dad's friends called him, "John, did you know Jimmie is going up and down 10th street blowing some kind of loud horn at everyone." That was the end of my air horns . . . fun while it lasted.

P.S. It got some attention from girls, which was the main point.
