I'm a bit puzzled by the following sugar sifter, as it appears to be hallmarked in the style of the sous-fermier pre-1789 (silversmith's hallmark struck three distinct times), however, the silversmith's hallmark uses the lozenge shape (post 1797?). There is also a swan (cygne) hallmark, likely due to the spoon being re-controlled at a later date. (The spoon weighs 80-90g, and is about 25 cm long).
I'm having trouble figuring out who the silversmith is - initials "GG" with a star above, and a flower below, all in a lozenge (see photo below)
I'm assuming that this sifter was made in the style of a sous-fermier at the end of the 18th century?
Any insight or help would be greatly appreciated. I'm very curious to learn more about this, as I didn't think this was feasible after the French revolution.
