Works with no cracks however outside looks like it was probably been through a war (they were)

Authentic vintage Japanese binoculars marked 7x50 with a 71° extra-wide field of view. Features serial No. 170 and maker codes J-B190 and J-E2, linked to mid-century manufacturers in Japan’s robust optics industry. These binoculars have a rugged military-style build with metal body, center focus, and original canvas strap.

Signs of heavy cosmetic wear as shown — paint loss and edge wear. Lenses appear intact but optics are untested and sold as is. A great piece for restoration, display, or parts.

7x50 = 7x magnification with 50mm objective lenses — a popular configuration for military and marine use due to its bright image in low light.

• 71° = extremely wide field of view (rare and desirable).

• J-B190 = Manufacturer code assigned by Japan’s optical industry — J-B codes refer to the maker of the body.

• J-E2 = Final assembler/exporter code.

• “No. 170” = Serial or production number.

• Logo (appears to be “UNYX” or “UNYO”) = Likely refers to Unyo Optical Co. Ltd., a known Japanese optics manufacturer that worked under various OEM labels.

The J-B190 body code points to Toko Seiki Co., Ltd., which produced a wide range of military and commercial binoculars. They often exported under various trade names or house brands. The J-E2 code suggests the assembler/distributor.
