M. H. Carpenter Company
With the United States entry into World War I, in 1918 the Phianna factory was used to make tools and dies for the Wright-Martin Aircraft Company. The Phianna company put its assets up for sale and Miles Harold Carpenter, an automobile enthusiast who had purchased a Phianna, with assistance from a Texas rancher, Carl M Worsham, acquired the assets. A new plant was set up at the end of 59th Street, Long Island City.[5]
Miles Carpenter was an automotive designer who had worked for Pierce Arrow and Chalmers among others in a varied career. The Phianna was hand-built including its four-cylinder engine of polished aluminum and a wooden cooling fan designed by Fred Charavey. An update version on a 125-inch wheelbase and a new radiator design changing from the Brewster style oval to a more popular Rolls-Royce style was ready for the 1919 auto shows.[5] The Phianna was a prestige car, prices ranging from $6,000 for a standard brougham, to $9,500 for a special touring car, to $11,500 for a limousine.[1]
Innovative safety glass was introduced in 1919 as were turn signals and stop lights.[5] Carpenter changed the company's motto from The Foreign Car Made in America to America's Representative Among the World's Finest Cars. The company also introduced an innovative six-cylinder engine in 1919 that saw limited production.[5] Phianna could list owners such as the King of Spain, the President of Brazil and Bainbridge Colby, Secretary of State.[1]
Miles Carpenter built Phiannas for Glenn Curtiss using the OX-5 engine with a view to setting up a Curtiss car company. With the depression of 1921 Carpenter, on advice from Mortimer L. Schiff, decided to stop production and close down the business. The final car was made in 1922 for John F Norman.[5]
