Where can I buy a large analogue meter? Big enough to show to a room of people, about a foot long pointer.

Use a small one, camera and monitor? Or just draw it digitally on a monitor?
I am sure there was one used in a willy wonka film.
A small one and a smartphone/tablet video fed to a decent sized screen.
You wouldn't be able to afford an analogue meter that large. Though you could build one from scratch in the true DIY fashion.
Model 8 Avo is about as big as they ever realistically get now.
ISTR Gallencamp (sp?) did larger ones for school labs back in the 70's. There is a Unilab 8" one +/- 50 uA on eBay right now.

ps : you didn't specify what kind of "meter" ... ;-)

Could do, but I remember a long long time ago when I was at school, the teacher had a voltmeter with a foot long needle. They must exist somewhere.
That would give it artificially increased sentimental value. I don't want to pay over the odds.
R/C servo with pointer, PIC with ADC, code.
get a smaller one and a video camera.
Big screen TV with an analogue representation of a digital reading performed in software.
Doesn't look so good.
I was in school in the 80s, and we had massive ones, looked like some kind of old fashioned weighscale from a fair. Very useful for the whole class to see the volts and amps in a circuit under demonstration.
Oops. Volts/amps please.
This shouldn't be necessary, in the 80s in school we had enormous voltmeters and ammeters for demonstrations. Just a simple coil meter with a long lightweight pointer.
It just isn't the same.
Make one yourself then. This is uk.d-i-y the clue is in the name!
Easier to press a button on Ebay, I can't believe nobody makes them.
Buy a few old ones on Ebay and pass them around. Depending on your budget, of course. It might be good for people to see the contrast in design.
I can't find anything over 6 inches. I remember ones over a foot.
They may well have existed then, but given the modern alternatives suggested by Jan that exist, I doubt there's a market for large meters now.

It just isn't the same. Would you buy a 6.2 litre electric car?
