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:) --- End quote --- Thank god! This has been haunting me. |

--- Quote from: Arbalist on May 20, 2015, 04:11:40 AM ---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. --- End quote --- I'm guessing it was originally kept in a case and used for calibration, not active battle use. It would be pretty clumsy and slow for that. So robustness not an issue. It's basically a caliper. Maybe this one, ex-service, was tossed in a drawer somewhere and got bent. |

Well done Joe - champion WWW searching. :D I had tried for hours and not found it. I have to say that I feel pretty smug that functionally it is exactly what I deduced, except that I had thought it for artillery (father being RA) than for small arms. Now I know where to start I can do some more research on it. Thank you very much Joe, and all the other contributors. |

Further info: Made by a company called "Allison-Gregory" or "Gregory-Allison" depending on source. This one is for fine sight adjustment in the horizontal plane, and is associated with setting up the sight for windage. I have found an antique gun dealer who sells Ventometers, and has a few examples of this exact model. One in good condition, as mine is, sells for £65, so it isn't entirely without value. The ventometers that work in the vertical plane are of a different design. |

Pete: Wish I could claim amazing Google-Fu powers, but as is much more normal for me, found it when I was looking for something else! But, at least now you know :thumbup: Cheers, Joe |
