The low profile Celtic putter also has a distinctly different, narrow at the heel wide at the toe, head shape. In addition to being stamped "Celtic,"  the top of the head is stamped "R. Forgan & Sons" with the Kings Crown, and "Special Putter / Warranted Hand Forged."  The 32 1/2" shaft is original as is the leather wrapped grip.  This putter also bears the "Chicago Golf Shop, Chicago" mark in an oval on the top of the head.
