I have a 1951 Farmall Super A that I am restoring. I have Guy's book that shows that the brake decal is supposed to go ~3" above the gas tank seam (page 132). But when I look at my faded gas tank, there is an outline of a decal that has the same shape and dimensions of the brake decal but it is located ~8" above the gas tank seam. In addition, there is a very faded decal below the brake decal that appears to be a round circle, about 3" in diameter, with a rectangular banner going horizontally across the middle (centered )of the circle that is about 1" x 4" and I can barely make out the word "Farmall" in the rectangular shape. Any ideas as to what that particular decal would be? Maybe some kind of dealer applied decal? After painting, I plan on installing my new Brake decal where the old one was located (8" above seam) rather than ~3" above seam like in Guy's book - would I be wrong in doing so?
