Remarks:

Made around 1960 by the British optics company Ross in London , this binocular with a wide angle of view features Porro II prisms (which were more common before the arrival of today’s highly effective antireflection coatings). The ease of view (“Einblickverhalten”) is excellent, the image is bright, but sharpness is not at par with the best binoculars of the period.
