Scottsdale 69BC croquet putters used a shaft that was either straight or bent to varying degrees--and this one features a significantly bend made by hand.
These putters were produced for a few years in the mid 1960s, but when the USGA announced in May of 1967 that croquet-style putters would soon be non-conforming to the rules of golf, production stopped—at no great loss to Ping because they did not sell many of these to begin with when compared to their conventional models. Today, however, because of their rarity and non-conforming nature, they are more desirable to collectors than many other 1960s Scottsdale putters.
This outstanding club in outstanding condition features its original shaft, Ballnamic shaft band, and Golf Pride grip originally modified by Ping to have a flat front, so the golfers thumbs could lay flat on the grip.
