"Gene, if you read this, should I start with the names and run them with the library in Hamilton County?"

Good as place as any. Ask for criss cross directories.

"The Game table list the club as having chips marked with a AC plain mold"
Spragg could tell you who made that attributation.
My guess if a AC plain mold exists with an ID, it will be on Rich Hanovers site.

IMO, there is no way in this world to attribute the AC Skey chips, said to be from the Alibi to the Alibi or anywhere else.
