An answer is needed
I am a New York City tour guide and a couple of days ago I had a passenger on my bus who disputed something that I always believed to be true. I am in the firm belief that over the years I read that Otis Elevators of Yonkers, New York invented and manufactured the side lift mechanism of the orchestra pit lift for Radio City Music Hall. The passenger claims it was Westinghouse. Please fellow Cinema Treasurers, what say you?
