Whittaker Bros., from Shaw in Lancashire, England, produced a
variety of simple coin-operated machines with interchangeable
perspex screens.
Two nixie tubes were placed in the eyes of various characters. Your
job is to put a coin in and use a button to stop the display on
winning numbers, to gain a payout.
I have details of machines various called "Beat the Blinkers", "Beat
the Bandit" and "Beat the Clown".
The machines featured a standard GPO (the UK Post Office) Strowger
uniselector, a bell-type system to step the selector and the two
nixie tubes.
