So that Boland single-reeler spins from bottom to top?

Little Duke or Duchess.
The overhung mech was easy to convert to single reel.

The thermometer on the one I remember was a translucent white, burnt to an orangey-red at the bulb end, where the lamp had been lit continuously for about ten years.

If the 'anti-cheat' relay has the same number of contacts, you may be able to press it into service as the missing 'payout' one.

I'm guessing that it's made from a Jennings Little Duke, or Duchess.

...shudder.

It's on Old Penny, with a 5/- token.
That's a rare combination for British use. Perhaps it was popular in Australia?
I'm sure Powell's Automatics could find you a suitable badge; or you could make one up, just like the old Operators did.

What a nice looking Arcadian.
This is what yooser27's belly glass probably said, before the Decimalizers got to it.
Is yours still on tanners?

There's an Aladdin's Lamp pusher on a well-known auction site now.
It's by CAM Automatics, I believe, which is one of my favourite manufacturers.
I remember it from the time, but I won't have played it much.

You get the hang of it very quickly.
