David is quite likely right, but your reference to the camera being with a dolly makes me wonder if the camera hasn't already been adapted to some purpose more portable.

If nothing else, you should go look at it, because they are fascinating, and great to work with (if you are into old style reprophotographic processes).

If you know anyone older with experience in the printing industry, they might be able to give you a lot of help.

If I was in Nanaimo, and you wouldn't object to 30+ year old experience that only covered a couple of years of use, I'd be happy to help.
