Greg,
Nice package in what looks like very good condition. It was built in 1972. Basically you have 3 different setups.
Things you should keep with the camera as a live shooting setup would be the mags, possibly one of the power supplies that may fit the Fries motor in box 1, any one of the lenses (most would prefer the 20-250 zoom), all the attachments in the second box: The thing with the hand knob goes on the bottom of the camera- it is a follow focus, the lens gear aligns with the gear on the follow focus and the chrome doodad on the side connects to an external sidefinder to correct for parallax. The one marked Panavision is a mattebox/lens shade and goes on the front of the follow focus so it can swing away (it may only work with lenses 4/5.)
Please visit our registration tab and register this camera as it would be the first of this type.

The camera itself has a video camera attached to the viewfinder that may also have the proper connection to one of those power supplies in box 2.
Box 3 is a complete animation setup with foot control. Some people may have an interest as would be the case with the #3 more recent Norris animation setup if either are functional- they can be modified for other cameras.
Other than as mentioned, the box2 power supplies are not worth much.
All the lenses are BNCR mounts that will fit a number of other Mitchell and some modified cameras. The number 4and 5 lenses are 75mm and 35mm prime lenses and worth more than the camera each. I am envious.
Lenses 2 and 1 are interesting early zoom lenses and one has a motor but no control seen.
Hope that helps. Do not hesitate to contact for any other information.
