Here’s San Francisco cable car #507 in the early 1950s at an unidentified location (from an original red border Kodachrome). Here’s what streetcar.org has to say about this car: “This cable car was built in 1893 in the East Bay town of Newark by Carter Brothers. It was numbered 507 until Muni dropped the first number on Powell cable cars in the 1970s. Car 507 served the Sacramento-Clay line until the 1906 earthquake and fire, and then was moved over to Powell Street, where it has run ever since, almost exclusively on the Powell-Mason line until 1956; on both the Mason and Hyde lines since 1957.” It was overhauled in 1957 and is still in use today.
