Thanks for the comments, guys, and thanks for looking! Augie, this is a model I built 40 years ago when I worked for the now defunct Dresser Industries. SWACO, the company I worked in, only made mud processing equipment, pressure control equipment, and some instrumentation, and this model includes all of the mud processing equipment on one mud tank and pump system. It sure would have been fun to build the drilling rig too.
Matthew, LOL, after the model was shown at OTC in 1980, someone in marketing got the bright idea to send it to some show overseas. It came back to me several weeks later looking like something Gerry Anderson DID blow up-- they wanted me to repair it. Once I surveyed the damage, I could see it wasn't nearly as bad as it looked. The railings were completely destroyed, and some of the equipment had come loose and sustained minor damage, but there was no major damage, and I got paid to work on the model for a couple more weeks.
