I am working on an update to my collectors TITO catalog published in 2004 and I would like to contact any collectors that have a large number of Oklahoma TITOs in their collections, and if possible ask them to review the 20 pages I have today of Oklahoma TITO issues planned for the new catalog version. Oklahoma is mostly a Class II slots state with many vendors in each casino issueing their own design TITOs and TITO like payout slips. Some casinos have a dozen or more types. Please contact me by Email if you can help in this update. Many thanks for any help.
