Would greatly appreciate help in determining maker on this silver spoon with black enamel handle.

marks shown are from a knife in the same pattern as spoon

Very worn, but I think probably Pierre Francois Queille; see forum posts Some French Advertisements and Information: Queille and Silver Goblet Identity
