In 1961, the Overland MkII was being fabricated and tested, prior to handing it over to the United States Army in 1962. The image to the left shows the large quantity of electrical wire gauges coming out of the Control Car. The MkII Control Car produced enormous amounts of current from the Solar engines (company name, not solar panels) connected to electric generators. The Control Car’s AC generator produced 150-KVA, 480 volt, 60 cycle, 3-phase, while the DC generator produced 600-V.

These images were captured at the previous R.G. LeTourneau, Inc. in Longview, TX.
