Chris, I just noticed your recent post to NavList about my confusion with the Vernier Scale on a Cassens & Plath sextant from a few years ago. What works for me is using the line with the "solid dot" as the reference ZERO for the vernier scale. I then use the rest of the marks on the scale as .1' ... I have used this with good results and this explains their error statement of .2' accuracy. Best of luck with your Cassens and Plath Sextant ... I love mine.
