Thought you might like to know more about the Macau chip I asked about. The correct name is Don Ravenscroft and not Ron Raven. Apparently a mistake on the records or Don not wanting his name used. Donald Chaucy Ravenscroft Sr. was a repairman at the TV repair shop that the chips were sent to in 1981 in Elkhart, Indiana. He apparently had them for private use since the only business he started was a refrigeration service company. He died in 1987 and his wife and children have all passed away since then. The widow of a cousin (Also a Donald Ravenscroft) told me Don Sr. never had a gambling place she knew of. She had no idea where the Macau name came from.

My note: I think DS is correct. Most TV repairmen could not afford to play in a game with $25 and $100 chips.
