I bought what I thought was an old Keno "basket" today at the swap meet. It has a "Mason & Co, Newark N.J." paper sticker on the bottom. It is a cage with wooden, numbered balls in it, with a hand crank. A mechanism at the bottom allows one wooden ball to be released into a recess in the wooden base. The thing is that the balls are numbered up to 90. I know that Keno has 80 numbers. Anyone know what the heck this is for? Any help would be greatly appreciated. Thanks, Doug in Kingman, Az.
