If you look on eBay for switchboard meters, you will find many with 270
degree movements. The eBay seller NRI Industrial often has them, and
frequently accept best offers for less than half of the asking price.
I use a standing search for:
(ge,G.E.,westinghouse,yokogawa,crompton) (meter,meters)
-(light,exposure,AC,alternating)
Just be sure to get DC meters. AC volt and current meters are a lot
more common, but they are very difficult to drive with a microprocessor.
The DC meters usually have a 1 milliamp or even 100 microamp full scale
movement inside, so they are easy to drive. They come apart easily, and
you can make and install a custom meter face without a lot of difficulty.

I was thinking about using a pressure gauge and replacing the bourdon
mechanism with a stepper motor. They have a wider rotation (up to 270
degrees) versus electric meters (typically 90 degrees).
