To state the obvious, it appears to be a sextant with the arc marked in feet! Never seen such a thing before. I assume it is a range finder
so I googled "rangefinder sextant" and it is a thing!
It lead me to this https://en.wikipedia.org/wiki/Stadimeter
and a A Mk 5 Mod 0 US Navy Stadimeter made in 1942 by Schick Inc. of Stamford CT. looks rather like the photo
A stadimeter of course is a range finder used with an object of fixed height
