Well done for the DB which you could call a breadvan too, Mike. One other strange DB was the "Vitrine", rather nice seen from behind imo.
If you're talking about chassis # 4491 GT, may be its this one:

As you suppose it went back to its original body before certification.
If you click on "making of" its about a report model.
