 | The S-5D was Leslie's first five-chime Supertyfon airhorn. Produced only in 1952, it played the
same notes as the Nathan M5. Two different manifold designs were used on the
S-5D. The one shown in the photo is the later version, with diagonal and horizontal bracing around
the two highest bells (the 554 and 440). Earlier S-5D manifolds lacked these extra pieces, with the
bells mounted precariously on "stalks" similar to the high profile J-base used on the
S-3J. Only a few S-5D's were produced before Leslie introduced its
replacement, the S-5T, in 1953.

Factory tuning was: A major dominant 7th (C#,E,G,A,C#).
The horn used Supertyfon bells #277, 330, 392, 440, and 554. The numbers refer to the bells' resonant
frequencies in hertz. In later Leslie production, bell numbers were truncated to just the first two
digits.

A few S-5D's survive today in private collections.
