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

If we're into artillery maybe we should consider milli-rads ??? http://en.wikipedia.org/wiki/Angular_mil No particular interest, just fancied poking my sneck in .... :thumbup: Yet another .... Dave |

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: |
