I think measurement of angle is most likely.
Well, nobody has said anything that might suggest an application other than calibration of ordnance, so I feel a visit to the RA museum coming on.
Thanks chaps.

Minutes or seconds was in response to Rob's suggestion of degrees - 60 seconds in a minute, 60 minutes in a degree .....

Google this war office publication:
"Abridged Treatise On the Construction and Manufacture of Ordnance in the British Service"
It's available on line as an ebook or you can get a copy - I'm sure that I have seen something very similar in that publication.

Scale markings shouldn't be regular spacing if it's angular on a flat, and vernier doesn't at all fit a non-regular division purpose either. Clearly bent arm is hardly ruggedized and one questions the need for vernier accuracy then, and the whole thing looks kinda low grade for what I think of as service quality.....
Nevertheless I believe best guess so far has been angular, and military, and sighting, cause things ain't always as they should be! Naturally, just sayin' this to create additional confusion! :lol: :lol:
