    Re: A10 sextant for sale
    From: Noell Wilson

    Hi David,
    There have been multiple discussions about the “C” size battery compartments in older sextants being too small for new batteries. I found that with my A-12.

    The summary of a recent series of discussions is at
    http://fer3.com/arc/m2.aspx/Dummy-Batteries-for-an-A12-Wilson-sep-2021-g51061
    With an eBay seller that will 3D print a slightly undersize AA to C adapter to order.
    I used them in my A-12 and A-8.

    Please note the recent cautions about A-12 corrosion. The two battery holders are very thin bare aluminum in bare aluminum holes. It’s easy to destroy the holders if they are stuck.

    In your search, also look for an A-11. It’s a stripped down version of the A-12 used for single sight training. No sight averaging mechanism, no gear train, no adjustable bubble mounting, and no scale lighting. Really simple.

    Regards, Noell
