Hey! I worked at that last place. I remember crawling around on the floor, packing boxes by hand.I won't fault these people or their process, it works for them..they are hard working and industrious folks, given the tools and equipment they have. I am very interested in your topic. It is very informative.Very hard working people. I only guess as to what the green blocks are. Maybe bath soap.Beautiful hand work, rewinding of starter motor armature coil. Keep it up.
