Vintage Meter ?

Could anyone let me know what this meter is used for no idea its cased in a nicge wood box looks good quality.

 

From the construction it appears to be a routine moving coil meter of some kind, possibly measuring amps, but the picture of the dial which might have helped is out of focus/unreadable.
It does appear to be of a type widely used in schoolroom physics classes, more or less unchanged since Faraday's day.

It is a good idea when posting pictures to also write out any text or symbols unless they are completely clear in the pictures.

 

It's probably a physics lab current meter. Using different shunts mounted inside you could read various current ranges. Having no scale the user would have to create one. With the needle in the it could have been a differential meter, showing postive and negative flows. Or maybe its stuck. Very old though, early 1900's ?

 

Galvanometer. The coil is stationary. Most likely for fairly low voltages at very low current.

 

True indeed the visible coild woild deflect the magnet on the needle, not the other way round. It does look pretty old but no different from the ones used in physics when I was at school. Of course, that was a long time ago anyway and the lab equipment was far from new then.
