Hi CEFrazier,
Interesting bandit.
Ruffler & Walker were
distributors of many coin operated machines and made a terrific line of allwins - wall machines, I'm sure we've all seen them -- flick the ball around the track and hope it lands in a winning cup.
The 1D is the imperial British (and Australian) penny, similar size as the US 50c.
Your machine would be one of the very last made under the 'Mills' brand as the original Mills company was long gone. TJM Co (
The
Jennings
Mills Company) I think was the manufacturer of this and that company made the last of the purely mechanical machines because Bally came to the forefront with their Money Honey (1963??). Then Ainsworth/Aristocrat here in Oz blew
them out of the water so to speak.
I think your machine is referred to as an M-Head due to the coin entry.
Happy to stand corrected on any of the above. Sorry, bit hungover this morning. Where's my coffee.
Regards,
