Other than this everything seems to work fine. However I intend to completely tare it down and recondition, repair, and replace everything.
After talking to it's last owner, I'm told it came from the University of Iowa who was probably the original owners. That's who they purchased it from.
About me, I'm a member of IATSE local 16 San Francisco since 1978 and a member of IATSE local 488 Studio Mech. of the Pacific Northwest since 1995. Local 16 is a stage and motion picture local and covers most all departments in film making. We also have Industrial Light and Magic in our jurisdiction. However they have become strictly CGI these days.
