The Leslie Horns operate on the same principle
as the Nathan horns and like the Nathan horns, they are available in three
and five chime combinations. Performance is similar to that of the Nathan
horns although some of the chords are slightly different as are the Leslie
part and model numbering designations. Just below is a Leslie five chime
horn, an RS5T horn. Nathan numbers their horn bells as 1 through 5 with
the higher number representing a higher pitch.
Leslie numbers their bells by the first
two numbers of the horn pitch frequency, rounded off to the nearest whole
number. Therefore a Leslie bell for A 440 is called a number 44 bell.
A Leslie bell for D# which is 311 Hz is called a number 31 bell. The construction
is somewhat different. Each Nathan horn unit is a stand-alone complete
horn. It is advisable but not necessary to use the manifold/bases. Leslie
horns are assembled onto the manifold which is also an integral part of
each horn, so it is not possible to use Leslie horns without the manifold.

Three views of a Leslie RS5T horn.
The side view shows how the individual horns and power chambers mount to the
manifold, the picture above shows the front view. Notice that the bottom of
the largest bell, the #25, has a slight cut-away flat on the bottom. This
to make it clear the roof of the locomotive cab. Hear it on test setup below.
