This is the very collectible Exakta model which was made for export and is stamped "Germany - USSR Occupied Germany".
The lens is a 50mm f2.0 Carl Zeiss Jena Pancolor. It is clean and clear but the focus action is stiff from non-use. The aperture blades are in excellent condition and work smoothly.
The shutter is crisp and sounds accurate at all speeds. The original case is included, too. It is in very-good to excellent condition both cosmetically and structurally.
