What are the switches from?
I'm guessing early metro 82-85 (not the earliest)
You're right I think they're from a metro. Originally i thought they were just a belgian type (as my mini is belgian made) but i could never find reference to them. Eventually i spotted them randomly on a metro parts for sale page.
Only trouble is............................................
Looking at it, I think the silver mounting plate is different to that of the mini so may have to swap that for my spare too.
