See Darts for Billboard articles about the introduction of this new-style cabinet to the pinball industry. The manufacturer's original playfield drawing (not shown here) is stamped ORIGINAL, is dated "Sep 22/60" (a combination of Steve Kordek's dating style and Harry Mabs' dating style), and has the signed initials for Mabs which would make him the draftsman. Unusually, the 'Approved' section for the designer's initials is crossed out and the name CARAVELLE appears instead of the designer's initials in what may be Kordek's writing. Also unusual is that there is no MASTER copy while the ORIGINAL has all of the usual tool room notations that would belong on the MASTER copy and shows completed "Oct. 25 - 60" (again showing the unusual dating style). Steve Kordek included this game on lists he would make of games that he designed but his name does not appear anywhere on the ORIGINAL drawing. Duncan Brown tells us that the scoring notations on this drawing show areas of Mabs' shaky handwriting but also Kordek's writing, and he adds:"There is no way that Harry would be doing simple draftsman's work on a game for Steve [to approve as the designer]. Harry must have started the design. But just as clearly Steve was definitely involved in it too." Harry Mabs retired from Williams on 10-28-60, three days after the tool room work completed for Caravelle and prior to its production. His last game for which he is credited as the designer is Magic Clock from December, 1960.
