An old carousel video I have, probably from the late 1980s, shows two
Wurlitzer organs at the Knott's Berry Farm carousel.  A Wurlitzer 157
placed outside the carousel was not playing.  This organ actually
looked to be placed in its own housing up above the entrance to the
building.  But there is also a Wurlitzer 153 at the center of the
carousel, which was playing on the video and hopefully still is
playing.
