Antique Solid Silver Alcohol Weighing Chest XIX Century Wine Calculation Rule Hydrometer

  

Ancient 19th century oenology instrument set. A solid silver alcohol scale. (Not hallmarked but tested by my professional workshop). A thermometer and a calculation rule. Marked "Berard à Lunel" (in Gard).

Wooden (walnut) case with insect holes. The silver instrument shows dents and a weakness (crease) on the graduated part (see last photos). In its original condition, dust, stains, needs cleaning.
