Graflex Super Graphic with good bellows.  Rotating back (you can't rotate with the Polaroid back on because of dimensions so I rotated with back off in the picture).  Rangefinder is accurate.  Shutter is working.  Video shows shutter at one second.  Optar f4.7 135 mm lens.  Camera has tilt and rising front.  Camera is currently equipped with a polaroid back.  Nice 4 x 5 camera.  This camera originally could also be used with a battery powered shutter.  They no longer make the appropriate battery so that feature can not be used any more on these cameras.
