The triangular box section contains a bubble level exactly like the Admiral Gago Coutinho system albeit only one. I was hoping someone out there would know about the square section adjuster adjacent to the bubble slot.Does it alter the size of the bubble. In 2010 someone posted on this forum saying he owned a sextant with a 2 bubble system. I may have a punt on eBay but postage from the States is high.
