Little is known about the history of this truly unique skeleton log car; only one photograph is known to exist. It is believed that a string of these cars were hurriedly built and added to Carter Brothers 4 foot swing motion trucks after the 1906 earthquake that destroyed much of San Francisco. These cars were used to haul freshly cut logs from the Boulder Creek area - from the Dougherty's Mill - to a yard on the South Pacific Coast line, from where they were shipped on to San Francisco. This kit includes Carter Bros. Trucks, sprung couplers and wheels.
