    Source for precision level vials for AH use
    From: Randall Morrow
    Date: 2012 Mar 1, 12:13 -0800

       I have found a source for precision level vials for AH use.   The vials can be purchased separately and they are accurate to 10 seconds, pre-filled permanently and have permanent scale lines already applied.   I was quoted a price of $50.00 plus $20.00 for shipping which makes them cheaper to buy than to make yourself after factoring in the time it takes.   A degree of personal satisfaction is lost however.    The company information is below:
    Level Developments Limited
    Tel : +44 (0)20 8684 1400
    http://www.leveldevelopments.com

    Their web site is also interesting but you will have to make e-mail contact for this type of transaction because they are focused on commercial rather than individual orders.  They are located in the UK and all communication I have had with them has been cordial.    They also have a .pdf that describes the process of adjusting a precision level vial.   The price I mentioned is only for the glass vial itself and you would have to make a spring clip or other means to keep it from rolling or hold a pair of them against the mirror surface.
