    Re: Sextant Repairs
    From: Graham Dodd
    Date: 2017 May 11, 07:35 -0700

    I have a 1995 Sewill's Cetus Prima sextant.  Unfortunately I have damaged the locking nut for the horizon mirror adjustment screw.  I have contacted Sewill's of Liverpool, C.Plath of Hamburg (whom I am told manufactured the sextant for Sewill's) as well as a number of other companies associated with the manufacture of sextants.  Unfortunately none carry spares and none can offer any advice, I am now out of ideas as to how to replace either the locking nut or even the whole mirror assembly.  Can you assist please.
