Engine One is a 1922 American LaFrance pumper that served Larchmont from 1923 to 1947.

The Larchmont Fire Department sold the pumper in 1947, but in 2002, its volunteer fire companies together repurchased it from a Seattle, Washington family. In 2007, the companies donated the pumper and other memorabilia to the Larchmont Historical Society. At the same time, the family of Jacob Orans donated $75,000 in his memory to aid in the restoration of the vehicle.

The Historical Fire Company conducted research, raised additional funds, hired a contractor and oversaw the restoration of the pumper. In 2012, Firefly Restorations of Hope, Maine finished its work, and Engine One returned to Larchmont.

Since then, the Larchmont Historical Fire Company has continued to maintain and display the pumper at community functions and parades. Company members acquired uniforms based roughly on those worn in the Civil War era by the Fire “Zoaves.”  They march in parades with the pumper, dressed in bright red jackets, black slacks, white spats and red illuminated helmets.

The company has also developed the Engine One website as an archive of articles, photographs and documents related to the pumper and its service to the Village of Larchmont.
