A recent post on an English website briefly mentioned your band organ:

Very few organs built by the Niagara Musical Instrument Manufacturing
Company survive anywhere.  It seems that most of what is known about the
company comes from one small 1911 catalog.  I posted information about
the instrument on Mechanical Music Digest (MMD):

If you were located more centrally, you could expect the organ to draw
visitors on day trips.  Please preserve this instrument.  I would also
invite your local curator to join the mechanical music community.
