    Brad,

    That binocular is completely new to me.  Is it custom to the sextant?  Does it have an interocular distance adjustment?  Is one eyepiece missing?  Were the two haves independent of each other like a pair of Navy night glasses, or did one side have an adjustment plus a control that adjusts both sides together, like more common binoculars?

    I can't read the label in the photo, but the clamping mechanism and the shape of the label say Heath Hezzanith.  The diffuser looks pretty much the same, but the magnifier swingarm is different.  The biggest difference is the frame - mine is of the three-ring type.  Any idea of its age?  Bill Morris helped me date mine as a 1905 unit.

    All zeros - pretty impressive.  Mine was recertified in 1940, with three zeros (15º, 105º, and 120º), four -0.2' (30º, 45º, 60º. and 90º), and one -0.4' (75º).

    Stan

    Hi Stan
    Here's a view of it, on the sextant
    The inspection certificate lists 0 minutes 0 seconds for arc error, every 15 degrees of arc.
