So, it is the display part of some sort of early 'betting' game. There are 4 lights, numbered 1-4, a big solenoid which rotates a drum showing various 'odds'. The drum appears to have a number of connections - not that dissimilar to an 'enigma' style encoding drum.
I'm open to any guesses as to how it was played, I'd love pictures of anything similar
My plan is to make it 'function' in some way..
This is the back showing the drum and the solenoid.
