OTIS Elevonic 411M???? @ DoubleTree Hilton Newark Penn Station

I am not sure if this is an Otis Elevonic 411 or not, if you know, please check the comments below Brand: Otis Year Installed: 1977 Year modernized: 1990s? Fixtures: EPCO Flush line I suspect that these used to be OTIS Lexan elevators years ago, when the hotel was built. However, they modernized it in the early 90s. The other 2 cars were keycard locked and had an additional modernization.
