Hello
Your vermeil spoons were made in Paris by François-Pamphile Josan (Jozan) maker of small tableware at 19 rue Simon-le-Franc. His mark was FJ, symbol two crossed boatman’s oars with a pellet on each side (deux rames de batelier en sautoir, un point de chaque côté). Josan first registered on 12 August 1824, erased 7 January 1836. He continued at another address with the alternate spelling of his name and a different mark until 12 March 1847.
See Arminjon, v.I, no. 01147, p. 141 and no. 02037, p. 215, and
