These posts originally appeared at my Ghost of Gardner Island site, which focuses on the Nikumaroro Hypothesis. My initial interest was in determining how the Brandis serial number series evolved with time. My research led me down several interesting (to me, anyway!) side quests that probably aren't of much interest to those interested in the Nikumaroro Hypothesis. So I've moved my posts about sextants, the sextant maker Brandis and Sons, and related topics here.
