    Re: A-10 Sextant Maintenance Manual
    From: Bill Morris

    Alcohol will not do for most A10 bubble sextants, which are fitted with vapour pressure bubble chambers, but will work with the A10-A, which have air chambers.

    Xylene will have to be used in those few bubble sextants in which the light path of the heavenly body passes directly through the bubble chamber, since the refractive index of xylene is close to that of glass.
