The O rolls that are three-digit numbers beginning with O-100 are
usually composite rolls made by Play-Rite in the 1970's.   These rolls
were made up with some of the best titles.

Most of these rolls contain songs from Capital Rolls.  These were
sold as Columbia Rolls in the early days before the name change
[November 1924].  There were also tons of A and G roll composites made
with these three-digit numbers.  The A rolls were made from Clark as
well as Capital and many others.  The G rolls were Clark (Automatic)
and Capital.  Nickelodeon roll collectors love the Capital arrangements
which are hard to find for A and G machines.
