From an FAA website: "December 1952.. "Old Tower Number Five" has now become Tower Number Seven. Old towers never die and when this facility was replaced by Tower Number Eight it was dismantled and stored along the southwest area of Perimeter Road. At the time of the Cuban Missile Crisis it was reassembled at the "old" Tamiami Airport and used until the "new" Tamiami Airport became operational."

In other words, this tower (old #5) served MIA in this new location from 1952 until the new tower (#8) on top of the new Miami International terminal was put into operation in 1959. This tower was located in the area of where Concourse "F" is today. Tower #8 was vacated by the FAA in 1985 in the move to Tower #9 on the west side of MIA. It was then occupied by Pan Am ramp operations until December 4, 1991 when Pan Am died. After a quick remodeling job on the tower cab we moved two of our Aviation Department gate controllers and two American Airlines apron controllers into the tower at the end of January 1992 and renamed it the "E-Tower" since we already had gate controllers in Eastern's former large ramp tower on Concourse B at the "B-Tower."
