look in www.sciencekit.com.
They have several transparent projection meters, depending on what quantities you are measuring.

Subject: demonstration meter
I am looking for a large analog meter to use in demonstrations.
I would like something that is a foot or so wide, pretty big.
I have been searching the web and not found much. I think I
am looking for a giant "switchboard panel meter".
I have seen references to projection meters (to be placed on
an overhead projector) but cannot find a supplier for these
either.
Any suggestions would be appreciated.
