In the 1950s, when coin piano rolls were no longer available from
normal sources, J. Lawrence Cook set up a business on his own as the
Perforated Music Roll Specialist.  I thought these images of his
business correspondence would interest MMD readers:

(1) envelope in Cook's handwriting to one of his customers,
(2) rate card, front side, with the lists of rolls available,
(3) rate card, back side, with a most incredible list of machines
    that were to use these rolls.

The list of machines on the back of the rate card touches on brands
seldom or never heard of and I feel the information important enough
to share with fellow collectors.  Should there be any interest in the
actual catalogue lists and roll numbers, please contact me directly.
I am happy to share.

Sincerely,
Ken Vinen, Aylmer, Ontario, Canada.
