I am not a historian, but let me add some information about Wurlitzer
band organ rolls that I believe to be correct. When I was a student in
the early 1950's I worked Summers for Playland Park in San Antonio. My
principal job there was operating the 4 row C W Parker "Grand Jubilee"
carousel, which included the care and feeding a double tracker Wurlitzer
146 band organ. Playland Park had purchased the 1917 carousel in 1940
from Ralph Balaban, who was a former manufacturing supervisor at Parker
in Levinworth Kansas. Ralph had worked at Parker from the 1920's until
Parker folded in about 1933. After that he brokered and maintained large
amusement business hardware.

The Playland Park 146 had about 75  style 150 rolls. Some were labeled
Wurlitzer, some Parker, and some Bacigalupi. Balaban maintained the
equipment twice a year and in 1953 I asked him about the source of the
rolls. He told me that Parker was a shameless showman who repainted and
relabeled most things with his own logo. He said that Parker bought
all his organs from

Wurlitzer and Bruder and repainted them. He told me that in 1929 just
after the stock market crash that he and several of the Parker crew went
to North Tonawanda and bought out most of Wurlitzer floor stock, parts,
and some tools including some style 150 master rolls and a production
perforator.  Parker then assembled about 20 organs from the parts bin.
Parker also punched some style 150 rolls using the Wurlitzer masters
and perforator at the Parker Levinworth factory. Balaban said that
when Parker folded Francis Bacigalupi of Oakland California bought
the master rolls and production perforator. Bacigalupi set up the
perforator and produced rolls under the Bacigalupi label.

I know that Wurlitzer officially sold the organ business to Alan
Hershall in about 1946 or so. From personal contacts in the American
Band Organ Association I learned that  that Wurlitzer really went out of
the band organ business in 1929 but that Ralph Tussing, who was the
Wurlitzer shop supervisor, talked Wurlitzer into letting him and some of
the workers continue to use the building to build and maintain Wurlitzer
organs as a sort of sub-contract business. This group built organs that
were labeled and shipped as Wurlitzer organs but none of the workers
actually worked for Wurlitzer at the time. This lasted until the start
of W.W.II.  After the war Hershall officially bought out Wurlitzer but
made a deal to sell (at a low price) the business  to Ralph Tussing in
return for supporting them with maintenance and parts for free.
