Yeah! This one has been kicking around for years! I am not sure who did the work, but it has been put together from a collection of parts from pre-war and post-war cars. Not all the cars were BMWs!
I believe it was intended to be a "Southern California Custom" restoration and not an "original" one. The overall effect is not all that bad!
I don't know the chassis number, but most of the original looking parts suggest it may be in the 739XX range with a pretty stock looking 55ps engine.
