The Silver Wraith received modifications to its F-head, six-cylinder engine. The bore was enlarged bringing the displacement size to 4887cc and horsepower to 178. They had a four-speed automatic gearbox, hydraulic front brakes, and hydro-mechanical rear brakes. The coachwork for the Silver Wraith was provided by Hooper, Mulliner, and Park Ward. The bodies were made of steel and rested on a steel frame. Some of the custom bodies were given aluminum body paneling.
This automobile is a H.J. Mulliner Style #7356 Touring Limo and was originally purchased by Mrs. Grace Vreeland Brown of San Marino, CA. The current owner is the second owner. The car had an 18-month restoration, completed in 2003.
