Look at the picture--doesn't look like a cut down to me?
Be tough to have a black border all the way around in a cut down.
Given the present condition, I doubt that its a reproduction, so my first thought is real.
My question would be why single sided in a pole structure, unless there were 2 back to back?
If Randy has an original example, that should verify the existence?
Maybe it should be remeasured? 1/4 inch difference?
