|The S-3J was Leslie's first
three-chime Supertyfon airhorn. Produced only in 1952, it was a derivative of the five-chime
S-5D. Both horns were designed to play the same notes as competing M-series horns from Nathan -
the S-5D versus the M5 and the S-3J versus the M3.
Leslie soon found its own voice, though, and the S-5D and S-3J were dropped from the catalog
in favor of the S-3L and S-5T. |
The S-3J also used the early, high profile "J" base (manifold). Other horns also used this base, and their designations have the J in the suffix position, unlike all other Leslie bases whose letters appear in the prefix position.
Factory tuning: A major triad (C#, E, A).
Though produced for less than a year, the S-3J found application on
several railroads. The L&N, Illinois Central, Frisco, Rutland, and the Vermont Railway are
believed to have purchased the horn before production ceased. None are known to still be
in use today.
