That would make sense, because all the parts stamped M-337 are primed. Were all the Skymasters built in the Wallace Plant? Was that the only plant they were assembled?

As you carefully look at this aircraft it leaves a lot to be desired in the streamline, finesse arena. In some places it looks like they had some last minute thoughts on some straps and patches here and there. It's definitely a aircraft that was built for utility and not looks or speed. It's airframe strength was tested with the military use and I like the idea of how strong the whole frame is rather than built for speed and looks like Bo's or Moo's.
