This description by John Farrell sounds very much like some of the
rolls that J. Lawrence Cook made at home on his one-punch perforator.
I've had several that he gave me and they fit that description.

The ones I have are, as I recall, for A-roll machines.  I haven't
played them in many years but think I still have one or two of them.
I believe he also made some "O" rolls that, except for the 9/inch
spacing, fit the same description.

They certainly were not up to the quality that I would have normally
expected him to produce.  I believe that part of the problem was that
he had no instrument to play them on to actually hear the results of
his endeavors.  On one that I had, and may still have, there is a
portion of at least one piece where it is obvious that several measures
were omitted and the tune has a strange sort of discontinuity to it.

Shortly before he died we had talked of making some Wurlitzer rolls;
I was nearly finished with an index plate that I was making for his
perforator, but of course that project never was fulfilled.
