    Re: Artificial Horizon, K & E USN No. 6

    Forgot to include description of the jug and all.
    The basin is cast iron .  The jug also appears to be cast iron. The top
    also seems to be  cast, but the inside is quite polished and threaded.  I
    guess I never realized that cast iron could be threaded and shaped so
    The hood/ triangular prism has glass plates in a light weight metal frame.
    I saw a similar AH (different supplier)  that was sold by an antique dealer
    in England....maybe.  My USN No. 6 is quite similar to the one sold, but
    certainly not in pristine condition. As I said it is missing an internal
    There is also a similar one at a museum in Australia ( I recollect).
    As far as pictures.....my computer skills are "challenged".
