Set of 6 tarn white wine glasses 13.8 cm in diamond cut crystal from saint-louis

This superb set of 6 crystal white wine glasses comes from the saint-louis manufacture. They belong to the "tarn" service of saint-louis, this model was created in 1957. It is a pretty intermediate-sized stemmed glass that serves white wine. The rim is richly cut with diamond and point patterns. They measure approximately 13.8 cm in height X 6.5 cm in diameter at the rim. In very good condition, I note scratches from use and a chip on one glass. Some series of this model are not signed or difficult to see. There are small manufacturing defects on some: discreet bubble or small dot in the crystal.
