Thank you all very much for your ideas and suggestions. I think that I am probably right in thinking it is a calibration device for artillery. It's purpose would be something like fine alignment of the computer to the cradle or the piece, so only a very small scale would be needed. It is conceivable that it might be for the setting up of indirect fire equipment. I think that a visit to the RA museum is now on my to-do list. Peter |

Found it! This thing is a ventometer, used for adjusting military rifle sights http://www.militaryrifles.com/britain/MHVentometer.htm If you decide you don't need it, let me know :) Cheers, Joe (edited for crap spelling :doh:) |

Ahh, click! The fact that it isn't a sight itself and is removed solves all the questions I had re robustness, the measurement increments, why vernier, and wouldn't it block the view. It is a removable adjusting tool. All of those then are answered. But also as a tool for setting sights, it does relate to weaponry and angular measurement, as Rob said early on. |

Joe's link is pretty conclusive. I'm surprised though as it doesn't look robust enough and even looks bent in the first picture. |
