This Buell B5 plays an uncommon A 7th Major chord. One of only three made. In 1983 Fred Berry a very well known collector in the early days paired up with Roy Buell the founder of Buell Airhorns and decided to design a custom five chime air horn. This is what they settled on after it was all said and done. The first five chime Buell and only three were produced. It has all custom length bells tuned to A Major 7th and a custom high mount manifold. This horn is one of the three that were produced while the other two reside in other large collectors hands. #buell #buellb5 #airhorn
