    Re: Image of Sextant Used by Worsley
    From: Bill Morris

    Thanks, Brad.
    
    It looks like a Mark I bell sextant frame with the Hezzanith rapid reader. 
    It's the first time I've seen a sextant with five index shades. The Galilean 
    star scope seems to have a relatively large objective for the time, with 
    screw focussing.
    
    The painting, by Arthur Shilstone, is quite close and shows Worsley using a "X 
    1" 'scope, i.e. a sighting tube (pace George Huxtable). I hope I won't 
    infringe copyright by posting an image of the front cover, for purposes of 
    review...
    
    Calibration of similar quality Hughes sextant is proceeding - slowly.
