oldog,
There was a little material left on the top cushion of one seat from a 1953 1/2 ton Panel (in storage since the mid-70's). It has a medium-grained leather "pattern" and is brown with a tinge/shade of maroon.
I do not know anything about the possibility of this being the same color from 47-52? I think the Suburban seat color was maroon in 1953 (and I know it changed to a maroon/gray combination in 1954).
