Shirley Englehorn was a professional golfer, active on the LPGA 1959-79. Somewhere along the line Sears set up a sponsorship deal with her, and the 535-312540 reel was the result. This is not mine, it belongs to a friend on a FB group but I thought it was interesting.
They're not seen very often so evidently there wasn't a huge demand and not very many were made.
