Pair of late 19th century salt cellars in silver metal with blue crystal lining

Pair of old salt cellars (late 19th century / early 20th century) in silver-plated metal by goldsmith Armand Fresnais with baccarat blue crystal lining. Rocaille style and floral decor. The linings are in blue baccarat crystal but the labels are no longer there. Good condition with some oxidation linked to salt on the inside of the salt pots and on a spoon.
