About the best condition I've seen on this model. Response (ZT) 'zero twist' MI 615 Square Back is the model Nicklaus used to win the 1986 Masters. At the time, the putter head was about 30 % larger than most and had its center of gravity towards the center of the flanged blade (vs the heel). Putter is all original with very minor dotted touch-up to head edges. Like-new fluted steel shaft, like-new shaftband and like-new original Macgregor pistol grip. 35". .
