10/17/18 - This is a rare ZF 4 L scope from World War II, in fantastic original condition. These scopes were made for the FG 42, one of the most desirable firearms from the era. The original finish on this scope shows minimal wear, and the optics are crystal clear. The rubber lens cap is minty with no cracking. The adjustment knobs are fully functional. Exterior markings are "G w ZF 4" , "40820" , "d d x.". There's an "L" more centered on the scope. Guaranteed all original and authentic.
