    Fred wrote, about the Husun Mate-
    
      The later ones, from 1942 on, have quite a bit of
    | eccentricity in the arc; they may have let quality slip to increase
    | production for the war, not to mention the Blitz.
    
    and-
    
    | $300-500.  Then there are old U.S. Navy sextants.  These also have
    | considerable eccentricity.  They also are not as common as the first
    | two and often are in need of serious repair when available.  You will
    | see the ones needing serious repair go for prices lower than $300.
    
    ================
    
    Tell us more about this eccentricity in the arc, Fred.
    
    How does it show up, and what is its effect? Does it give rise to stiffness,
    over part of the travel? Does it affect the calibration?
    
    George.
