"16" during the 1839-1838 period was the department of Charente-Inferieure (now called Charente-Maritime), and there were two assay offices there, in La Rochelle and Saintes, the latter being distinguished by the addition a pellet or small raised dot in the mark alongside the numeral "6". The standard reference for the region - Elie Pailloux, Orfèvres et Poinçons, Poitou Angoumois Aunis Saintoige : XVIIe-XVIIIe-XIXe s. (La Rochelle: Librairie Pailloux, 1962) - does not show this mark; many of the insculpation plates evidently did not survive, and there was little interest in 19th century makers until the end of the 20th century. That said, I think the mark is indeed upside-down in the image but should read "IV" flanked by two pellets. It is definitely not Fouquet, though: in addition to working in Paris and not the Atlantic coast, he was only ten when the guarantee mark here was last used!
