In response to Rick Inzero's comment regarding the Auto-typist:
For years they were the best thing on the market.

The roll frame and much of the equipment was the same as some of that
used in coin pianos.  In fact, it is my understanding that one of the
coin piano companies actually made the Auto-Typist or at least portions
of it.

I've had several of them here, both the early models and the later
models.

I believe they were made originally to operate an International
Business Machine Co. model A electric typewriter, one of which I used
to have many years ago.  Of course, International later changed their
name to IBM but I used one of these in about 1950 when I operated a car
haul-away service at the Kaiser-Frazer plant at Willow Run, MI.  (Want
some more history?)

I later obtained on of my own and used it for several years.

The Auto-Typist rolls are 11 1/4 inches wide and when I was making
rolls in the early sixties I found a source of Auto-Typist paper
already cut to that size and it made excellent music rolls.

The Auto-Typist rolls, when punched, do not resemble music rolls much
as they use is single hole for each operation so you see no elongated
perforations, just a single hole here and there along the roll.

It was common for a user to have thirty or more "files" on each roll
as the rolls are about the same size as a long A roll.  If someone is
really interested I could scan a portion of an Auto-Typist roll so you
could see what I talking about.

I've given away several of the Auto-Typist players and some of the
others I used for various projects around here over the years.

I do still have a keyboard perforator for the Auto-Typist.  I had
another one but sold it with a piano that I had converted to play from
the Auto-Typist and that allowed the new owner to make all the new
rolls that he wanted by merely sitting down and keying them onto the
blank roll.

If someone in interested I could scan an Auto-Typist manual into a JPEG
file and send it.
