This horn is referred to as the "king of horns" due to its enormous size. The SuperTyfon measures over 3 feet across and is available in five separate horn configurations.
This horn is a smaller horn that is popular with collectors as a novelty item due to its low cost and nostalgic look. Although it is technically marketed as a train horn, it is also used on 18-wheelers and other large vehicles.
In 1954, AirChime Ltd introduced the 'K' series of train horns, which has remained popular to the present day, becoming the highest sold train horn in America by the year 2000. These horns are designated by the number of notes that are played when they are sounded: a K3 model plays three notes, while a K5 model plays five notes.
