This Worthington dimple ball mold was used to make Worthington Warwick golf balls. Interestingly, these balls are not listed in any of the golf ball reference books, except for the Dunlop Warwick ball. Worthington, however, also made a Warwick. This mold includes the Worthington "W" inside-a-circle logo above the "Warwick". The writing in the mold is in reverse, so the writing on the balls will read correctly.
