When this putter was first produced, it was referred to as the "Chantilly Putter," after Chantilly, France, the home of its inventor, the Marquis de Chasseloup-Loubat. Jean Gassiat was the French golf professional who worked at Golf de Chantilly, in Chantilly, France. He was a champion golfer in his own right, defeating Harry Vardon in 1912 to win the French Open. Gassiat used the Chantilly putter as did others.
This example is marked "Jean Gassiat, LCL model, Regd no. 6277302." The registered design number dates to the end of 1913. The "LCL" in British aristocratic honorifics, refers to Lord Chasseloup-Loubat, the inventor of the club. Most of the known Gassiat-style putters are not marked Gassiat or LCL Model. This one is early.
The club has its original shaft and early pistol grip, which is described in an October 31, 1913 Golf Illustrated review as an "extra thickness at the top for the use of the left hand."
The finish on this putter has been nicely reworked, the rays of the wood grain visible on the crown adding to the beauty of the club. A great early example marked with the right names.
