Old Carl Zeiss Jena 10x50w best Binoculars

Product Name: Old Carl Zeiss Jena 10x50w best 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. best 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. Lastly, there is an aroma of age to these binoculars. :) 6.5” x 7.5”.
