A nice pair of mid to late-warKriegsmarine'smooth ocular' binoculars, as often issued to and seen in use with U-boat crews etc.They are nicely marked with the Carl Zeiss Jena maker code 'blc', as well as still retaining the vast majority of the original factory-applied black finish throughout.Optically, there is a fracture to one of the ocular lenses, as shown - but, as is to be expected with quality Zeiss binoculars such as these, the coated lens optics still remain in really good working order to this day and produce a wonderful bright and sharp image aside from this!
