This vintage Leica m-mount Ernst Leitz GmbH Wetzlar Summarit 5cm (50mm) f/1.5 manual focus prime lens comes with both of its caps. There is a number etched into the side of the barrel (please see photos). There is also haze inside near the center of the lens. The exterior of the barrel has a couple of light scuffs on it. Its focus and aperture adjustments are both smooth and its glass is free of any fungus or separation to its elements.
