My '56 panel was a U. S. Army mail truck. I found the "milspec" plate on the glove box door, but nothing in the glove box. It was gone. In the back, there's a little "shelf" up along the roof line. There must have been 20 or more 35mm film cassettes in there. They were painted gray and had a bunch of odd numbers on them but nothing else. Who knows what was on them or if they had been used. The film inside was melted into a brown mass.
