Villiers headlamp switch

[R]

Bit slow here, need something to git thungs movin agin ?

Anyone care to explain the Villiers headlamp switch ?
Waratah/Excelsior 125cc circa 1945

I thought it was a Miller, but new/replacement has a chrome ring around it.
And would be (slightly) too big to fit ??
What retains it - a large wire circlip ?

I'm only slow because I'm spending too much time in the shed doing a 50-year service on my recent acquisition... the clue is that it has more grease points that any bike I've ever encountered.

This headlamp is 5 1/2 ", and the switch hole is 1 3/4 "
Anyone know what (Miller ? ) switch this is likely to require. ?

Dunno Leon, tell us ....

Whiting V4 - just had it's first run around the block. Although I did ride it 25-odd years ago!

Hmmm, thats a fairly exotic beast !
And it does have a few suspension points that would require greasing.

Is there only the one and only ?

There's another survivor, powered by a 5hp JAP v twin, and with a Jardine gearbox. It's a nice original bike. This is the only one with Mr Whiting's own V4 engine, and his own 2-speed gearbox.
