Hi MMD,  A couple other individuals and I are working on a master
list of "O" rolls.  If anyone in the MMD audience has any old "O" roll
catalogs they would be highly appreciated.  I can copy and return them.

Has anyone done any writing on the history and origin of "O" rolls?
How many companies produced "O" rolls?  I have located some old
catalogs for Play-Rite but not for any of the other companies.  Any
info would be appreciated.
