Evidently from the measurements this is not a Model A windshield frame. Anyone know what it is for? Measurements on frame are: 41 5/8" wide 15" tall on the sides 13" tall in the center Also, the material seems to be stainless steel.
Looks like 'a' to me, the 28-9 shared a frame; 30-31 shared a different one. That looks like a 28 sedan to me. I just checked the measurements and the 'a' is wider.
