Wm Gibson Gem Putter w/Shaped Wood Grip.  The 34" Dangowood shaft in this Gibson gem "muscleback" putter also forms the grip.  It is flat with two notches on its back side and hollowed/grooved out on its other three sides.  The shape given to the handle was designed to facilitate the golfer's grip. The grip area is stamped "Mauophit" (that's what it looks like to me...) and "Danga Wood". This club is a beauty, in well above average condition.
