Yes, it would be show-stopper in a parade.

What’s a string stop?

@@Vladimir82623 A rank that is built and tuned with certain overtones in mind to imitate a string instrument, like a violin.

@@Karlfalcon oh that make sense also when they punch the rolls out what type of notes do they use do they use piano, organ or what scale

@@Vladimir82623 Roll, book, or barrel organs normally do not have a fully chromatic scale, so they would not be able to play a piano roll. There are many different specific scales for organs, depending on how they were built.

@@Vladimir82623 look up the 20-note organ scale for an excellent example of how small organs can play well with so few notes available!

+Musicmany2k Yes, it is. I purchased it in 2011.

Song at 7.15 = "Amapola" 😊

Thanks for your interest Jack! Great question! Wurlitzer band organs use both pressure and vacuum (pressure to play the pipes and vacuum to operate the roll system); others, including the one on this video, use pressure only. That's why you see a roller with grooves holding the paper against the tracker bar--otherwise the pressure would lift the roll away from the tracker bar. The pressure system was a 1920s innovation by the Artizan Company, one of Wurlitzer's competitors. It simplified the organ's system by eliminating the vacuum pump. Later, after Artizan ceased operations, the B.A.B. Organ Company continued that system.

Craig Wiley Thanks for your reply. I first saw one of these marvellous instruments when I was about 3 or 4 years old on a carousel at an amusement park near Detroit. Couldn't get it out of my head. They have some in Holland, Michigan and during the tulip festival in April they have a parade that features many of them. Glad to see that people such as yourself are restoring these magnificent old organs. Thanks again. Jack Clarke

I agree.

it used to be a a barrel organ
