Jim,
I think you missed my point. I don't think that you know what happened
during the assembly process on a day to day basis unless you were there.
I'm not saying that trucks were delivered without paint. I meant they
might have been assembled without paint if need be. Obviously an extreme
situation. However I would not be surprised if it did occur.
I just visited with my wife's Aunt today. She worked at the Ypsilanti B24
Bomber plant during the war. (She is 86) She can tell you some stories
about what they did to get those bombers out the door.
I can guarantee that what was suppose to occur did not always happen.
This is a link to a description of the plant and the neighboring plant
where I worked as an engineer during the late 70's. We still had the WWII
blue prints for the buildings in the plant at that time.
