Hello everyone,
Recently I've been to a local historical museum when visiting my parents back in Ukraine. I've seen several navigational items (see numerated photos below) but could not identify them in details.
FIG_1 and FIG_1 a: It looks very much like a sextant frame but degree scale goes from 0 (in the center of the arc) till 35 deg to the right and to the left. There are engraved words: "course" and "drift to the right". A circular frame ( FIG_1 a ) has four cardinal directions and concentric circles. It is not clear if you can turn it but I suppose so. In the description it is just said that this is "a navigational instrument". No idea what for is this instrument.
FIG_2: It is said in the description that this is a marine sextant (19 century). It looks like theodolite although theodolite can also be used for measuring altitudes of celestial bodies.
FIG_3: Perhaps from the shape of the sextant frame it is possible to identify this old sextant.
FIG_4: Last but not least an old historical photo - John Howard https://en.wikipedia.org/wiki/
kind regards,
Igor
