Default 9-0-9 DC Ammeter (Application?)

Some years ago i was given this Ammeter and am curious about the precise application/s.

(Legend reads 'AD6586 Made in USA By US Gauge Co NY')

Assuming a linear response it is of around 9-0-9 Amp range, and the clamp on the rear, it appears, originates from elsewhere. (probably a cad. plated capacitor clamp)

The meter is brass, with a hefty glass which has an angled edge. The flange has 3 holes, and has traces of paint similar to what you might call 'Allis-Chalmers Orange'.

The zeroing is best when the meter is set horizontal, and i suspect it may have been used in early tractors. They have changed hands on ebay in the past, but i can't find any good lead as to the machinery which they were used on...Can anyone can shed any light on this?

Thanks
Dave
