The German Army and Navy used a wide variety of optical equipment, including a 6×30 (6 power magnification with 30mm objective lens), 7×50, 8×30, 10×50 and others, being the standard issued optics used by all branches of service. Though this type was the standard, specialized personnel required stinger optics, and were issues to personnel on a limited basis. This specific binocular was used by U-Boat crews, ships, and coastal artillery. Made by Leitz Wetzlar of a large tooled alloy and aluminum construction, these 7 x 50 power binoculars are in EXCELLENT used condition! The lens bodies retain about 95% of their original, rough textured covering, as well as the original paint/finish! The aluminum end piece fittings are 100% intact, however one of the eye cups is missing (easy replacement)! The focus adjustment still functions perfectly on both eye pieces and the optics are still VERY clear with MINIMAL spotting! The left eyepiece has some brown dirt/oil marks around the inside and outer edge, which can be seen when viewing through the lens. It is not in the body itself, or on the prisms, so it should be quite easy to rectify (would need the eyepiece removed to clean). The right side body is well marked with the impressed KM Adler markings and “N” – indicating North Sea use. Left side is marked with a ” T ” (indicating the optics are coated), along with 7×50 and E. All the stamps are quite deep with some paint chips on the edges. A NICE example, with. NO cracks, breaks, or damage! A PERFECT addition to any collection or display!! Most of my items are vintage, and as such are AS-IS, so you must therefore expect a degree of wear due to age and/or usage. ABOUT ME.
