    Zvi,
    
    Bill Morris blog is
    http://sextantbook.com/category/how-flat-are-sextant-mirrors/
    Look on the right for the contents: SNO-T, Chasing the fractions of
    minute, and there is much
    other scattered info, where he describes comparative frame tests
    of several sextants, and where we speaks on calibration with
    collimators, and where he speaks on comparison of backlash
    and drum excentricity for various sextants.
    
    But most of the information on comparisons are in his books
    that are for sale: "The nautical sextant" and "SNO-T book".
    Yes, he has a whole book completely devoted to SNO-T.
    
    How much does it cost in London, do you remember BTW?
    There are several potential problems with Russsian (I mean former Soviet
    Union) sellers. They usually do not accept Paypal.
    Their English can be poor. Transportation is expensive and non-realiable.
    Some of them can even be fradus, but these go out of business
    quickly. Look at the reputation ratings in e-bay.
    All Russian dealers I dealt with were extremely helpful, friendly and
    honest.
    If you don't like all this, you can use Western sellers, in London,
    or this Dutch guy:
    http://www.santik.eu/sextant_divers_en.htm
    or elsewhere.
    Of course you pay more if you buy from a Western seller: there is no free
    lunch:-)
    
    Alex.
