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.

Used to be in every school physics lab.
These days a USB voltmeter or even a USB scope will be cheaper.

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.
But everything gets smaller, large meters take up space fine for demos (wonder where the royal instituition Xmas lectures get their stuff from) I assume yuo mean things like this.

but nower days for price and size, we bought 100 meters to send out to our students during covid so they could work from home, cost under £3.

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.
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?
