A few Wurlitzer Style 150 band organs were outfitted with duplex roll
systems when built and more were retrofitted at the factory when they
were returned for service.  One was sold by G. W. MacKinnon in 1970
and another was released from carousel duty in the mid-1980s.  They
all seem to have disappeared, their whereabouts unknown today.

I would be pleased to hear from anyone having possession of a Style
150 duplex, or knowing where one might be located.  The need is not to
acquire one, but to bring a knowledgeable end to an ongoing mystery.
Confidentiality, if desired, will be maintained.

Thank you,
