Exceptionally clean Polaroid 450.  Polaroid #490 Focused Flash, 2 Hi Power flashcubes (8 flashes), user manual. Comes in a Polaroid case designed for 400 series cameras.   

The 450 is the last and best of the Automatic Land Cameras, introduced in 1972 and sold through 1976.  It has the most advanced shutter.  The development timer on this one is accurate.  I have owned (and sold) many Polaroids.  I keep a 450 for my use.  

The camera has been converted to AAA batteries.  Changing the batteries does not affect the camera's operation, but does require connecting the shutter and development timer to a single source.  Polaroid used two batteries to guard against the possibility that the timer might short and discharge one.  I've only seen it happen once.  

Sample photo was taken in Fredericksburg, VA July 4.  Everything is working as designed.  

The Focused Flash is the most advanced bulb flash ever.  It incorporates a louvered blind that dims the flash as the camera is focused closer, automatically adjusting flash intensity for distance.  It also has adjustment for exposure compensation.  Hi Power flashcubes are twice as powerful as the M3 flashbulbs used by earlier Polaroids.  Includes new batteries.
