Original WWII U.S. Marine Corps Mark 46 Binoculars 7x50 by Bausch & Lomb - Dated 1944

Item Description

Original Item: Only One Available. This is an excellent condition pair of WWII USMC Mark 46 7x50 Binoculars made in 1944 by Bausch & Lomb Optical Company.

This model of binoculars were nearly identical to the U.S. Navy Bu. Ships Mark 28 Mod.0 7x50 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 28 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:

MARK 46, No. 18867, 1944

Below this is the manufacturer information: BAUSCH & LOMB OPT. CO. ROCHESTER N.Y. U.S.A.. The left rear plate is simply marked 7 x 50.

The optics are clear and excellent, all aspects of the binoculars function, and they are in overall excellent condition. The black canvas neck strap is supple and strong without defect.

Overall a fantastic Marine Corps issue wide angle 7x50 binocular set from WWII.
