Among the most popular golf collectibles is the giant niblick. Even
non-golfers view it in amazement as its size is so eye-catching. Giant
niblicks were produced primarily during the 1920s. This example was
made by Cochrane, and has Cochrane's Bowline knot cleekmark on the back
of the head which is also stamped "Mammoth Niblick,
Warranted Hand Forged, Fort Mason Picadilly London, Stainless". The face depth
measures 3 1/2 inches. The shaft and leather-wrapped grip are original and the head still shines, in excellent condition. If you have trouble making contact with the ball, this is your club!
