Jerry Pell's restored Gebrueder Bruder Model 103 fair organ,
previously owned by Steve Lanick, came with many boxes of
67-keyless book music.  A few of the music books were still
playable but many needed major repairs and copying.

Virtually all of the music books apparently were arranged and
perforated by unknown musicians working for firms such as Berni,
Molinari and B.A.B.  The folding media was assembled with
(aniline?) red cardboard stock until the late 1920s when B.A.B.
changed to green cardboard stock.

The holes of the 67-keyless system are spaced exactly 6 holes per
inch, just like Aeolian Pianola rolls.  The width of the cardboard
travelling through the reader is nominally 304 mm, or 11.97 inches.
The width of each page of the book is 165 mm, or 6-1/2 inches.
Historian Fred Dahlinger believes that Jerry's organ and a sister
organ owned by Wil Markey were built in 1912 or 1913, just before
the start of the Great War in Europe.

The song titles have disappeared from many of these books and book
fragments and so Jerry hopes that the tune experts reading MMD can
identify them.  Please listen to the music at the MMD Sounds site,
