Wurlitzer Style 148 Band Organ Brass Pipes

To further an understanding of the resonator length of the Wurlitzer
and North Tonawanda brass resonators, I sent a photo to the editor
of the Style 148 Wurlitzer Military Band Organ displayed at DeBence
Antique Music World in Franklin, Pennsylvania.

I used PhotoShop to overlay the note name, note number and position
on each bell.  As you can see in the photo, the two longest, smaller
resonators are actually in the middle of the range.  In organ terms,
these are 'harmonic' or double length resonators.  It is quite common
in church organ trumpet and tuba ranks to go double length on the
treble pipes.

In the Wurlitzer and other band organs, to get the nice symmetry in
the display, the length of the foot sticking out of the reed boots are
a variety of lengths.  This aligns the fronts of the bells into the
nice display.

If you were to lay out the boots in order, the shallots continue from
large to small without any apparent break where the resonators go from
full length to double length.
