    Hello Allan,
    If it turns out that the liquid had evaporated from the bubble chamber over the years, I have a PDF of drawings and instructions by Mr.Bartlett from Austraia on how to remedy this. I wish I had this file when I fixed the bubble on my MkIX...
    Let me know.

    Hi, Does anyone have any info on how to repair/maintain and then use a 1942 MK IX A Bubble Sextant, I'd like to learn Astro and take some sights on the land.  Alternatively can you point me to any useful sites/links, organisations. The one I've just aquired seems to 'work', most controls move, some a little stiff though. The clock work mechanism runs down over 2 Mins. However I've no bubble. Thanks for any help.
