This is a Kodak Six-20 Duo Camera with the Compur-Rapid shutter and Anastigmat Lens 1:3.5 f=7mm.  This is not a series II, this is the Art Deco!  Shutter releases and seems to work.  Bellows seem intact.  Lens has about 50% haze.  Viewfinder is cracked (see photos).  This camera has not been tested.
