    Re: The Observer’s Book on Astro-N avigation - Coutinho sextant

    As promised, I have now written a blog post on the Coutinho pattern bubble sextant here: https://sextantbook.com/2016/05/06/a-coutinho-pattern-bubble-sextant/ I look forward to comments and corrections, which I hope will be kindly made.

    Next in line is C Plath's earliest sextant type.
