The o/u barrels on my Grand America have a very similar bracket. I can only assume its to ensure the barrel stays tight against the forarm wood. Sort of like how later adjustable rib unsingles have wood on both sides of the single barrel. Not 100% sure if this is the case but it sort of seams that way at least on my gun.
It is there to help hold the barrel tight to the forearm. Here is a pic of the CT measurements that goes with the barrel. Chokes numbers 5,6,8
