This rare vintage Jules Carpentier Photo Jumelle Monocular camera uses 6.5x9cm plates. It comes with 1 plate holder. There are a couple of light scuffs on its exterior. There is haze inside of the lens, but it is free of any fungus or separation to its elements. Its shutter functions properly but its timing device does not. The rear wooden panel on the viewing side is cracked. Please see photos.
