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.
