It's a stadimeter, a device to determine distance to an object of known height. This one is very sextant-like, but the scale gives it away.
On the wikipedia page there's a 'Mk 5 Mod 0 US Navy Stadimeter made in 1942 by Schick Inc. of Stamford CT.' that looks a lot like it.

P.S. Look at the man's name tag!
