The production of the Rolls-Royce 40/50, also known as the Silver Ghost, started in 1921 in the United States to reduce manufacturing costs and void hefty import duties. In 1925, the Phantom I was introduced in Britain and a year later in the United States. It had many similarities to the Silver Ghost but had a more modern long stroke, OHV engine. Production would continue until 1931 after 1,240 examples had been built in the U.S.

This car is an American-built Phantom I Chassis from the Rolls-Royce factory in Springfield, Massachusetts. It has Newmarket coachwork by the Brewster Company, located on Long Island. Brewster was purchased by Rolls-Royce of America in the early 1920s, and it was responsible for building most of the body styles on the Phantom I. The Newmarket was a rather formal six-passenger convertible style and was very popular at the time. This car was first delivered to a Mr. Ogilvie in December 1930 toward the end of Phantom I production.
