Its original to the very early 9N's. Both my early 9N's are this style. Ford realized really quick that top links were weak and kept breaking off when the farmer hit a large object in the ground when plowing. That is why it was changed to a top link that has a much large boss in it.
The image that is posted is from a three digit AL hood tractor that is currently being restored by a good friend of mine. instead of the top link breaking off the casting shattered leaving a 6" hole in it. I think he did a hell of a job making it look original again. He also does have the control spring for it.
