Fully tested in good working order.  Wollensak Synchro Alphax Matic shutter.  Shutter speeds good all writing visible not worn.  Aperture adjusts smoothly no issues.  Aperture blades clean.  Mounted to silver Technika lens board.  Optics clean and clear.  Faint dust and cleaning marks not an issues normal for a lens of this age.  Cleaning marks are normally seen when the lens is scoped.  Using condensed light to see glass characteristics and how the light travels thru the glass.   Cleaning marks appear in a circular pattern normally.  Its exactly what it sound like clean marks from cleaning the lens.  These marks are faint and will not affect image quality.  Overall very nice optic and shutter. See photos for many clean views of the actual lens we will ship.  Photos show how well this lens deals with contrast.  Images shoot thru lens front and back.  Very sharp snappy images.  This lens has excellent resolving power shows detail and snap in photos.
