Reproduction leather binocular neck strap. This includes 2 studs to attach it. Made in Europe from high quality leather, complete with period correct markings. I would not own a pair of binoculars without a strap. This will work with most German binoculars including the 6X30 and 10X50 to name a few of the common ones. Might be the only German item that was truly standard across multiple applications.
