I read in the Archives about someone adding wooden trombones to
a style 105 band organ.  I have Doyle Lane's book of Wurlitzer pipe
data, but I am not sure of the resonator lengths needed for trombones
to add to the 105 bass pipe section.  Maybe Robbie can help, or
possibly someone else may have information.

I have built a MIDI version of a 105, and I have 55 pipes now playing.
I am aware that the 105 normally uses cello pipes to supply the
missing higher frequencies to the bass pipe, but I thought it would
be interesting to try trombones instead.

Thanks,
Burl Updyke
