Up for sale is a Leitz Wetzlar VALOO lens hood with adjustable aperture control for use with a 5cm f/3.5 collapsible Elmar.  The hood is in very good working condition with minor to moderate overall wear, the worst of which is a series of small nicks and paint loss along the rim (easiest to see in the last photo).  Please be sure to fully enlarge the provided photos, and feel free to contact me with any questions you may have.
