In 1919, the company incorporated as Rolls-Royce of America and acquired its first US manufacturing plant in Springfield, Massachusetts. Production began the following year. By 1923, Rolls-Royce presence in the U.S. was substantial, with offices in Boston, Chicago, San Francisco, Cleveland, Hartford and Troy, NY, in addition to the original office in New York City. The company was further represented in 16 cities across North America. Rolls-Royce
of America Inc. manufactured nearly 3000 Silver Ghosts and Phantoms before succumbing to the Depression. To this day, Springfield is the only place outside England that Rolls-Royce cars have ever been built.
