Thanks John!!!!! This is by far the nicest chassis I've ever laid my hands on, or even seen in person!!!!! 
Yes, I believe the thick layer of dust, and I assume a heavy coating of cigar/cigarette smoke contributed to the preservation of this gem of a chassis!!!!! 
Funny tho. The dust layer was SUPER thick under the magical brain cover. Far heavier than what was on the power chassis!!! 
P.S. this was only a 60+ hour clean up, and it still really isn't quite finished yet, but it's as far as I'm going on it...
Oh, and, all switches, transformers, and everything else I checked was either spot on, or in tolerance.
