A large-sized marble (toy), typically 20mm or more. In Liverpool, a corruption of 'bottle washer'; the combination of spherical glass stopper and rubber washer used to seal a Codd Bottle which was designed specifically for carbonated drinks. Children smashed the bottles to retrieve the marbles.
Ay soft-lad! You can't play a cats-eye with a ordinary marble - you have to play another cats-eye or a bollywasher.
