14. 1 kg Gold bar, 999 purity, numbered 339110, marked Ancien Etablissements Leon Martin, 1975, accompanied by analysis bulletin

Very few ingots stamped with the name "Léon Martin" still circulate in the public space, these being collector's items, rare, historical. Léon Martin from Bagneux was not initially a gold refiner. He was a manufacturer of mechanical chains, in gold, white gold, platinum, as well as seamless wedding rings, as shown on some invoices. It is assumed that the activity of gold refining and manufacturing of pure gold ingots (24 carats) appeared later. Most gold ingots are stamped with the inscription "Les Anciens Établissements Léon Martin" and were produced at the headquarters in Bagneux, on Gustave-Courbet street no. 11. Jean Pourquery was one of the company's expert evaluators (assayers), before establishing his own gold refining workshop. The company had several variants of company stamps "Léon Martin". In one of them, the postal code 75003 (Paris), instead of Bagneux, is mentioned. Among the evaluators of the "Léon Martin" ingots stands out Jean Pourquery, who founded his own testing laboratory, later becoming a gold melting and refining workshop, active until today. After 1993, the company "Les Anciens Établissements Léon Martin" was taken over by the Bijoux Fix company.
