Today: I was wrong about how he came to have all the electrical parts. He bought all the spare parts that were in a closed Pfizer pharmaceutical production plant. The parts were there as spares to support the production machinery. There were an average of a dozen copies of each of various relays, micro switches, pneumatic actuators, etc, all very typical things used in assembly-line factories. In all there were about a half-ton of these parts, most new-in-box. The other half of the shelves contained machine-tooling such as very large drill bits and reamers, maybe 3/4 ton of it. It took me a few hours to get all the stuff on pallets and into truck and trailer.
