Rialto (Wulff) transformer

Opened up the Rialto and this is my first time looking at a European transformer.

What's up with those legobrick-looking things? Are those olden junction boxes?

I am thinking of swapping in a 120V transformer, assuming I can verify the wiring is the same as the Bingolette. PDF that has been posted elsewhere, where the two circuits are 12V and 30V.

Always disconcerting to find like 3 wires disconnected and floating there. I sure wish the wire colours were labelled in the schematics like in American pinball machines.
That one loose red wire runs to the solenoid that I believe releases the ball, so definitely a bit important. ;)
(solenoid K on the schematic, which I will also upload again here for redundancy)

Any advice for working on this one? Only ever worked on EM pinball before, and never converted voltage regions before.

Can't wait to get this machine up and running!!

OH WAIT the motor is powered by 220 V...

Colloquially known as chocolate box connector strips (because they look good enough to eat). They tend to be semi-transparent these days.

Here's the equivalent bird's nest on a (working) Bingolette.

Are those universally-used screw-type connectors seriously not known in America?
