Old Carl Zeiss retailer Jena 10x50w Binoculars

Product Name: Old Carl Zeiss retailer Jena 10x50w Binoculars
Vintage binoculars with case and leather strap. “Carl Zeiss Jena multi-coated Jenoptem 10 x 50w” I know nothing about binoculars but these were pretty awesome to use. Very clear and crisp. These were definitely used and loved with signs of wear on metal. Right lens shows two dots upon visual inspection, see photo 9. I can't see these dots when using the binoculars. All appears to be in good working order though some of the dials are stiff. Should likely be taken apart and cleaned. retailer Lastly, there is an aroma of age to these binoculars. :) 6.5” x 7.5”.
