S-I 1/4 Scale Model
Before there was the Marshall Space Flight Center, before there was even a NASA, the Army Ballistic Missile Agency began the Saturn program. In designing what would become to be the Block I Saturn I S-I (first) stage, they built a 1/4 scale model of the stage for use "in studying handling and assembly fixtures."
One day I was reading the Pictorial Progress Report, Saturn Program: [Vol. I, 1st Three Quarters 1959] [direct link to 48 meg PDF] on USSRC archives hosted by the University of Alabama - Huntsville, (or, as their web site would like it be known, the "Saturn V Collection, Dept. of Archives/Special Collections, M. Louis Salmon Library, University of Alabama in Huntsville, Huntsville, AL" -- it's easier to just say the UAH archive :-) and came across a couple of pictures of this model.
I thought the pictures looked familiar, so I referred to my pictures the S-I Model at the Michigan Space and Science Center.
The two models do bear a striking resemblance, although the picture quality from the PDF images isn't good enough to conclude that the two models do more than "bear a striking resemblance."
