S07-006. French, mid 19th century, unsigned. The 13 1/2" x 10 1/2" x 3 1/2" polished mahogany case has a plush-lined removable tray and the set contains over 40 original pieces. The case and its contents are all in very good overall condition, noting that the wire on the hydrometer pan needs to be re-soldered and the contact goniometer is missing.
