Welcome to the forum , New Age Picker .
Nice old B&L binocs .
Yours appear to be missing the eye-cups (rubber) .
Here's an image or two , similar to yours , used by the U.S. Army Signal Corps in the WW2 era , priced currently @ $21.50 .
The coatings on the prism case (main body) on these are notorious for deterioration , often due to acids & nitrate (gunpowder) residue on hands (also from all the rough & dirty conditions found on the ground during war) , as well as exposure to sunlight .
