Smooth champagne flute from the 1860s

Height 16.5 cm. Fine antique champagne flute from the 1860s. It has a polished pontil underneath, where it can also be seen that it has been clipped. The glass is without decoration of any kind and has a very fine weight. We have not been able to find it in any of our catalogs, but we are relatively sure that it is Danish. Item number: 11913
