OLD SOLID SILVER ALCOHOL SCALE 19th CENTURY WINE CALCULATING RULE HYDROMETER Areometer

  
Ancient 19th century oenology instrument set. An alcohol scale in solid silver (not hallmarked but tested by my professional workshop). A thermometer and a calculation ruler.

Marked "Berard à Lunel" (in Gard). Wooden box (walnut) with insect holes. The silver instrument shows dents and a weakness (crease) on the graduated part (see last photos). In its original condition, with dust, stains, needs cleaning.
