Yes it is the 2102-D . The pictured US Navy model is from the late 1950s and has a brass pin rather than the nylon pin on the 1960s version. I find the 2102-D most useful when modified with a combined ZT hour and Aries month back template (homemade from a file folder). This saves NA look-ups. Plot the Sun every week or so and make short work of displaying the twilight sky and figuring Sun sextant presets during the day. Works good enough to earn a place in my sextant box.
