French makers. Unfortunately I do know little of French makers in early days, but wooden "Régence" and "Staunton" sets have been made in France in the cities like Dortan, Oyonnax and Saint-Claude in the Jura in huge quantities, up to 250.000 per year in Dortan in the mid 50ies, because boxwood was present in huge quantities. This was important for chess set manufacturing in the late 19th and 20th centuries. Henry Lardy, being the biggest, Ernest Vincent (in Dortan), Pichon-Vincent (trade mark Phidias; the oldest family chess maker in Dortan), Henri Chavet (in Moirans-en-Montagne), Michel Roz, Vauchier et fils and Jurabuis are all chess set manufacturers. Likely there were some more. Henri Delaire (successor of Numa Petri) did sell sets, but was not a turner.
One of the first turners in Dortan using Galalith is Charles Vauchier, because he has been listed like this in the village directory since 1926. Others are Durand Frères 1929, Henri Chavet 1932 catalogue, Ernest Vincent 1936 ad (maybe exist before). After the war all the turners could offer Galalith. Both my French Galalith sets are most likely made by Chavet. They are quite hard to find and I do not think they were mass produced. Pieces had to be turned and carved by hand and they usually come in a suitable cassette. And I wonder what the price of Galalith was in those days? Most likely these sets were already expensive at the time.
Henry Lardy (1898-1962) became in 1921 the manager of the turning company that was founded by his father in law in 1890 and renamed it H.Lardy. It was situated in Dortan in the French Jura. In 1925 the company made it's first chess set. Their dominance of chess set making was in period 1930ies till early 1970ies, when they sold their sets all over the world. Late 1980ies they stopped producing chess sets, because they couldn't compete with cheap sets from India. Apparently their shop closed in 1992. The Lardy pattern has been licensed to many other manufactures around the world. See for instance Hempfling “Staunton” (Germany) or Homas 20st century (Netherlands). Lardy chessmen were available, felted and unfelted, as well as weighted and unweighted. They ranged in size from the small set with a 2-3/4” King, to large Club-size sets with King heights over 4-3/4”. Next to the Lardy pattern with it's characteristic Knight ("Tète fin"), they made also better quality sets with Knights ("Parisiens en une pièce") having glass eyes and sets with simpler Knigths ("Tète oridinaire"). See for instance “Staunton” (France).
