Leslie S5D

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-5A. Then, both models were replaced by the S-5T in 1953. 
Here is a sound sample.
