Marriott Hotel in Memphis, TN has Haughton Elevators modded by Dover & Otis

These were also filmed by bcelevators. I didn't see his video take of these until after we had visited Memphis. It was very surprising to hear the Otis voice but the elevator had Dover fixtures. :) If you haven't checked out bcelevators yet, be sure to check out his channel. He has some pretty good videos.
