Anatomy of a WurliTzer Theatre Pipe Organ
Each Stop Switch on the Switch Stack was labeled the the Stop Name,
in this example "Sole Trumpet 16 2nd", the range of the stop relative to
the range of the rank "1-49" indicating that this stop used notes 1 to 49
(because the trumpet was only an 8' rank so the 16' stop started at Tenor C
on the keyboard and used the first 49 notes in the rank)
The other number "889" was the Wiring Schedule number.
