Antique crystal port glass, Caton model

It was at the st louis factory that it was named "caton" in 1877. Height 10 cm diameter opening 6 cm diameter foot 5.6 cm. Weight 142.5 g. In very good condition (much thicker than current crystal) unsigned because it dates from before 1936. Weight of the set before packaging: 142.5 g carefully sent france and export.
