  • Original Item: Only One Available. This is a very nice original U.S. Navy WWII 10-power Officer-of-the-Deck Spyglass, Mk. II, dated 1942 and complete with its matching wooden transit case. Both the telescope and case are serial numbered 6630, making this a particularly desirable matching set. The optics remain clear and the focusing mechanism continues to operate properly.


    The telescope is a refracting optical instrument, using an objective lens at the forward end of the tube and an eyepiece at the rear to produce a magnified image. Instruments of this type were well suited to shipboard observation because of their relatively simple construction, narrow profile, and ability to provide useful long-distance magnification.


    Refracting telescopes typically have a lens at the front, then a long tube, then an eyepiece or instrumentation at the rear, where the telescope view comes to focus. Originally, telescopes had an objective of one element, but a century later, two and even three element lenses were made. Refracting telescope is a technology that has often been applied to other optical devices, such as binoculars and zoom lenses/telephoto lens/long-focus lens.


    This is a great example of a 1942-dated Officer-of-the-Deck Skyglass, Mk. II. This is the MkII Spyglass, with a serial number of 6630. The optic lenses are still very clear and still able to be focused properly. There are markings present on both the telescope and the case. The data plate on the case reads:


    FEE AND STEMWEDEL, INC.
    10 POWER OFFICER-OF-THE-
    DECK-SPYGLASS, MK. II
    U.S.N.-BU. SHIPS
    SERIAL NO. 6630


    The telescope is marked over the adjuster:


    U.S. NAVY
    BU. SHIPS
    O.O.D. 10-POWER
    N.G.F. TYPE
    NO. 6630
    1942


    Both the spyglass and wooden case bear the same serial number, making this an excellent matching set. The transit case measures roughly 3 ½ x 3 ½ x 25” with both latches still functional.


    The combination of the 1942 date, U.S. Navy Bureau of Ships markings, matching serial number 6630, clear and functional optics, Fee and Stemwedel transit-case plate, and original fitted wooden case makes this a particularly complete example of WWII U.S. Navy optical equipment. The matching case and telescope are especially significant, preserving the instrument as an intact wartime set rather than as an isolated naval optic.
