Pictured here is a 1966 Beetle painted in "Lobito Blue" and had a "S" stamped on the VIN plate. The same colour and code was also used in 1965, but was named "Strato Blue" which probably explains where the "S" originally came from. All cars painted "S" also had blue interiors as standard, except for certain Kombi models which had grey as an option. Not sure if the "S" code was used on earlier cars as well.
