I can appreciate that people do collect the lower COA, but, the way I see it, the LA51 for instance, if it was the genuine number one, the model would have the aerial, as it was after they were released that the aerials were removed.
From what I see in the pic, I cannot realy tell if it does or does not have it.

I also noticed that the antenna appeared absent. However, the hole for it may have been added to the production run after the Proof was examined (?). Remember, the Canadian version didn't have the hole or the antenna, and I believed that they were issued around the same time.
