This sextant is based along the same lines as the Bureau of Ships Cruver lifeboat sextant. It is made much more complicated however. For instance, the fina adjustments are made using a worm gear (with plastic tooth on the scale of the sextant). The adjustment of the indexmirror looks very complicated with a rotating mirror. The filters are of sturdy plastic, something their succesors usch as the Davis MkII and the Ebbco can learn from. It has a simple sighting tube ad the handle is uncomfortable at best. It came in a wooden box but I'm not sure that is original.
