Originally referred to as the "Chantilly Putter" after Chantilly, France, the home of its inventor. The Chantilly putter, however, rapidly became known as the Gassiat putter. Jean Gassiat was a popular French golf professional who famously defeated Harry Vardon by a stroke to win the 1912 French Open. Though the shape of this putter often leads people to refer to it as a "croquet style" putter, croquet style golf strokes were effectively outlawed by a 1910 R&A ruling, so it is doubtful that this club would've ever been used croquet style during sanctioned play. See The Clubmaker's Art (2nd Edition) by Jeffery B. Ellis, p. 537.

This Gassiat putter has the "Jean Gassiat" script stamp on the head. The putter is in very good overall condition, and was likely produced between 1913-1920.  32 1/4"
