Pretty clear that Bernard Dibble had a lot to do with this story, which has art that is completely different than previous "Kelly Poole" stories. However, Dibble is not credited on Bails for this.
Script and art credits per Jerry Bails' Who's Who of American Comic Books 1928-1999, verified by Terry Gustafson, son of Paul Gustavson, who also provided the lettering credit.
