Original Item: Only One Available. This is an excellent condition pair of WWII U.S. Navy Mark 32 Mod.2 Binoculars made in 1943 by the Universal Camera Corp in New York, New York and was specifically designed for the Bureau of Ships. U.S. Navy organizations that were largely responsible for procurement in 1940 were designated Bureaus, each commanded by a Rear Admiral. These Bureaus included: Aeronautics, Engineering, Navigation, Ordnance, and Ships. So the fleet of surface combat and support ships, of submarines, of Coast Guard and of Maritime Service vessels, along with most of their instruments and consumables too, were largely specified by and contracted for by the Bureau of Ships (BUSHIPS, or sometimes designated BU.SHIPS)

When the mission was to observe movement across a wide expanse of air and water then a binocular with a much wider field of view was justified. Several wide angle binocular models were commissioned specifically for the Bureau of Ships whose vital work included spotting enemy vessels, planes, as well as other objects; these bear the designation BU.SHIPS as found on this example. The Mark 32 was a version like the original Bausch & Lomb Mark 1 produced for the Navy, but with improved waterproofing and different prism plates.

These are marked on the right side of the rear by the eyepiece with the model and serial number:

They come complete with a beautiful used condition M24 carrying case with shoulder strap. All in all a beautiful example of a set of U.S. WWII officer field optics!

Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military models.

Unlike a (monocular) telescope, binoculars give users a three-dimensional image: each eyepiece presents a slightly different image to each of the viewer's eyes and the parallax allows the visual cortex to generate an impression of depth.

Binoculars have a long history of military use. Galilean designs were widely used up to the end of the 19th century when they gave way to porro prism types. Binoculars constructed for general military use tend to be more rugged than their civilian counterparts. They generally avoid fragile center focus arrangements in favor of independent focus, which also makes for easier, more effective weatherproofing. Prism sets in military binoculars may have redundant aluminized coatings on their prism sets to guarantee they don't lose their reflective qualities if they get wet.

One variant form was called "trench binoculars", a combination of binoculars and periscope, often used for artillery spotting purposes. It projected only a few inches above the parapet, thus keeping the viewer's head safely in the trench.

Military binoculars of the Cold War era were sometimes fitted with passive sensors that detected active IR emissions, while modern ones usually are fitted with filters blocking laser beams used as weapons. Further, binoculars designed for military usage may include a stadiametric reticle in one ocular in order to facilitate range estimation.

There are binoculars designed specifically for civilian and military use at sea. Hand held models will be 5× to 7× but with very large prism sets combined with eyepieces designed to give generous eye relief. This optical combination prevents the image vignetting or going dark when the binoculars are pitching and vibrating relative to the viewer's eye. Large, high-magnification models with large objectives are also used in fixed mountings.

Very large binocular naval rangefinders (up to 15 meters separation of the two objective lenses, weight 10 tons, for ranging World War II naval gun targets 25 km away) have been used, although late-20th century technology made this application mostly redundant.
