    Re: Seeking advice for bubble repair on a Plath aircraft octant

    Thanks to Bill's instructions (by private mail) I was able to "re-
    create" a usable bubble. Obviously it is still enough fluid in the
    system after 65 years or so. I am of course keen to learn how the
    sextant is disassembled (and vice versa). One day I will need that
    Thank you to the Ken and Alex advising as well.

    definitely refined ethyl alchohol (the same sort of alcohol that is used as a 
    social lubricant). As it is clearly derived from the Plath SOLD octant, the 
    latter almost certainly used alcohol too. I will try to post instructions and 
    pictures to describe how to remove the bubble assembly and refill it on my 
    blog (www.sextantbook.com) sometime in the next few days.
