To the 630 with supercharger only the mechanics were contributed by Mercedes, while the bodywork was provided by Park Ward, London. It is a so-called transformatnion convertible which could be opened alternately in front or at the back. Of course, it was also possible to remove the soft top altogether. For show purposes the passengers rode under a closed top while the drive's seat was in the open air. In the 1920s this was regarded as "all the rage", or what we now would call "cool". For outings in good weather the whole top was removed which turned the car into a big convertible.
