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.
