    Re: Mark IX sextant manual

    My abject apologies!
    There is a Mk IXB. It is as an A model but has a double time automatic 
    attachment. This can be set to take 60 shots in either 1 or 2 minutes. 
    The addition of am M (as in IXAM or BM) indicates a double eye piece, one normal and the other X2.
    I have never seen an official manual for the B model so I for one will be 
    interesting to see what arrives.
