With the factory mark in blue enclosing the date letter S for 1771 under the painter's mark of a crown for J.-C. Sioux l'aîné (active at Vincennes and Sèvres from 1752-92).

The central rosette, with its interlaced L's, is practically identical to the decoration of the dinner service supplied by Lazare Duvaux for use by Louis XV at Fontainebleau in 1757. That service was painted in monochrome pink and was regularly supplemented with additional and replacement elements, including in the year 1771 for which the tray is marked.

This tray being in monochrome blue is not a part of the Fontainebleau dinner service, but the decoration suggests a royal origin. The King's symbol of interlaced L's simply was not a symbol for others to use however we have found no documentary clues in the Sèvres manufactory's archives that relates to this tray.
