OK, last message re: Mapes roulettes. One of the "Wheel" chips I don't have is N6881 listed as "gray". And I couldn't find anybody at the convention who had one for sale or trade. Finally several people very helpfully looked at their records and no one had one in their collection. So, is this just a dirty/used/mis-described version of N6885 listed as "white" but really more like an off white??

Thanks again.
