Polaroid Integral back (possibly called CB-70 or CB-72) for Polaroid integral films (600, SX-70 / Time Zero, Artistic TZ, Fade2Black etc). Also works with The Impossible Project's new films - PX100, PX600 and the upcoming colour film. This back doesn't seem to work on any particular camera without some modification to the back itself and/or camera. Hopefully these pictures will be of some use to anyone undertaking such a modification. All measurements are in cm and are an approximate guide only - I might be out by a mm or so and different versions of the back might be slightly different sizes...
