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 and the club took on Gassiat's name.

Chantilly-style putters were eventually produced by a few other makers.  They were sometimes called "Grand Piano" putters as a more generic term. Today, they are typically called "Gassiat" putters no matter the name on the head.  This example was offered by Ben Sayers or North Berwick and is marked with his name on the crown.

The club has both its 32 1/2" original shaft, stamped "Ben Sayers, Select," and leather wrap pistol grip. This shapely grip 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 head itself measures 2 1/2" in width and 4 1/2" in length.

The finish on this putter is original and looks good. The face is clean. The sole has its original brass soleplate and three large circular lead weights. With its large, detailed head in such nice condition, this is an impressive putter!
