The trucks were built across the street at the Mertz company. We built the circuit boards from scratch doing all the soldering  for each unit that went out the door. When China bought 90 trucks, we had to build 90 sets of the vibrator control units plus spares. China sent their "technicians" and "truck drivers" to do a final runout of the trucks and get training on how to use the electronics. When they came in to the assembly lab on a tour, we had old model 1 design failure modules scattered about on tables and were soldering in components, to make it look like we were working. Every one of them produced a camera and started taking snapshots non stop. What they didn't know is that the circuit boards after assemble were required to be "potted" with black epoxy and encapsulated in metal containers. A team of us spent weeks trying to dig the epoxy out the containers and get to the components on the circuit boards. Used chemicals, knives, whatever, and were never able to deconstruct one of the modules without destroying it in the process. China's intellectual thievery has been going on for a long time.</blockquote>
