Slotted deep groove back spin irons were quite popular between 1916 and 1921, when the R&A decided to ban them from the game and the USGA made preparations to follow suit, which occurred on January 1, 1924. Made by Hillerich and Bradsby, this Par-X-L backspin mashie-niblick has stong stamps on the back, original shaft and grip.
A highly visual club in great shape!
