Graduated glass vase 1930

Charming vase, hand-engraved glass (h. Paris pouch and beautiful graduation figures up to 1000 ml) which was a large graduated laboratory glass from the 30s! Very good condition, beautiful shine, no cracks or chips, some microscratches down but nothing unsightly, a bubble towards the beak that is completely in the glass (see photos). A charming and atypical object! Height 23.5 cm, top diameter 15 cm, bottom diameter 10.5 cm. Very neat packaging, i'm used to.
