Will look into but probably no help. Photos of the fixture, get detailed and what is the problem or requested operation and maintenance you would like to do? Often betweeh fixture types, such things are similar.
The Color Arc 700 was manufactured by Ushio in Japan, also under the Xebex brand. They still make followspots, but current models are different. I would check with Ushio America to see if they can provide documentation for the Color Arc 700. You'll have to find the "historian" in the organization, and I'm afraid I don't know who that is--or even if such a person exists.
