    Re: Kollsman periscopic pendulous sextant

    No, no electric averager on these sextants. Still the same mechanical
    ones as on old bubble type. You really only need 3 Volts if you do not
    need the lighting in the gimbaled mount (28 V).
    Sextant partnumbers are:
    A28450-00-002 (Kollsman System-Technik GmbH, Muenchen, Germany)
    L28450 00 001 (Kollsman Instruments Ltd, The Airport Southampton UK)
    It is impossible to tell for me where these sextants differ.
