Got this one from Renomarvin, eBay ID for Bob Corse, whom I take to be a Reno area antique seller. Has anyone seen or have one of these? These are certainly pretty common but the serial number stamped into the inlay got my attention. I hadn't seen that before. Same 197 # on both sides but not what I'd call coin or medal aligned, just orientated to the inlay litho. I'm thinking Nevada Club casino workshop floorsweeper for some Lincoln Fitzgerald brainstorm but I'd love to hear of other examples or ideas!
