    A-12 Bubble sextant
    From: Jean-Philippe Planas

    Hi all,
    I just purchased an A-12 bubble sextant that seems in fine condition but features nevertheless a serious flaw.
    The Bubble Illumination Assembly (with a bulb on, and also named the Night Illumination Assembly in the manual) is stuck in the instrument thus preventing the removal of the bubble assembly in place (and also preventing any night shots as I cannot put a battery inside or change the bulb). I am also unable to clean this part of the instrument.
    Could anybody familiar with these instruments suggest a procedure to extract this Bubble Illumination Assembly because I don't want to do anything foolish that could damage the sextant or the assembly.
    May be Mr Ken Gebhart could provide useful advice to solve this probleme if he is still monitoring this list.
    Looking forward for any advice
