    Re: New Soviet era sextant SNO-T
    From: Bruce Cutting

    Sounds reasonable - Can you move the arc form minimum (0 degrees) the
    the maximum (120 degrees as I remember) - If not it needs some
    attension.
    You may be interested in Bill Morris's book on sextants - It pays
    particular attension to the SNO-T
    
    Cheers!
