The feet are perfectly round and have been made in a clapper - a production method which came into use around 1880, the stem has been made separately and the foot has been added. This single knop tableware was probably produced between 1870 and 1930, give and take a few years. Very similar items are found in the Holmegaard and Aalborg catalogues of that period - which serve as an identifyer for tableware produced elsewhere.
