The C couronné poinçon was a tax mark applied to alloys containing copper, between March 1745 and February 1749.
The C-scroll rocaille end mounts to this bureau plat are characteristic of the oeuvre of Antoine-Robert Gaudreaus (1682-1746, maître in 1708). The same mount features on the top drawer of a commode supplied by Gaudreaus in 1745 to the Dauphin for his bedchamber at Fontainebleau, now at Versailles (A. Pradère, The Art of the Ebéniste from Louis XIV to the Revolution, Paris, 1989, p. 147, pl. 118). A bureau plat of similar proportion and shape with nearly identical chutes, corner mounts, end mounts and handles was in the Wildenstein Collection, sold Christie's, London, 14-15 December 2005, lot 127 and later Blanchet, Paris, 26 June 2006, lot 268. A further bureau plat of similar form with nearly identical handles and crescent mounts was formerly in the Keck Collection, La Lanterne, Bel Air, California, sold Sotheby's, New York, 21 May 1994, lot 131 ($200,500). The same handles also feature on a commode by Mathieu Criaerd (1689-1776, maître in 1738) in a private collection, Paris.
Marcell or Marczell von Nemes (1866-1930) was a Hungarian financier, art collector and art dealer. He was born Moses Klein.
