1931 Franklin Series 15 Convertible Coupe

  • Chassis Number: 51207210L18
This Franklin Series 15 Convertible Coupe was purchased new by the president of South Boston Savings Bank, of Boston, Massachusetts. He drove it as his primary car until his unexpected passing in the mid-1950s. The car was then inherited by the banker's daughter and her husband. They would use the car extensively during the summer months. Their son would later become the next and current owner.

In the mid-1990s, the car was rebuilt. It was finished in its original colors. It is powered by an L-head, air-cooled six-cylinder engine displacing 274.2 cubic inches and offering 100 horsepower. There is a three-speed manual transmission and four-wheel hydraulic brakes.
