All true, but what amazes me (as someone who has spent a great deal of time re-making all this old stuff) is why me in my workshop with simple tools regularly finds simpler ways to make this stuff. Sometime re-producing the way they did it adds a whole new level of complication.

From what I have read on war time production, a lot of sub-assemblies were done in small shops pressed into war time production....... good being moved in large wooden bins or open top 45 gallon drums. Parts produced in large quantities by shops making only one or only a few sub components. Hooks for the tarps, hinge straps, pre bent partly welded fender well boxes, sub-assemblies of tail gates such as hooks, hinges, etc..... all to be joined (welded) together in a central plant. Spot welds were rarely dressed up like we would do today and unevenly spaced.
Very few small shops would have the means of doing the larger components like the head board of a cargo box or the long narrow drop sides of the cab 11/12 2B1 box.
Over time the design and assembly was modified to its most simple mode of manufacturing keeping in mind what could be done cheaply and as fast as possible.
