I don't know what made this device any different from a typical tape recorder. I checked Smith-Corona's current location, and they're now located in Cleveland, Ohio. Now 410 Park Avenue is the home of the Manhattan Business Centre. There is also a Maserati corporate showroom, and Ferrari has an office there, so it must be a good place for high-end car dealers. According to the website 410park.com you can rent executive suites for $2,500 a month or virtual office space for $90 a month. The head offices of the NFL used to be there, but they moved to 280 Park Avenue.
