Chinese blue and white bottle case, with a possibly cut-down neck. The mark is Ming, Chenghua period. The two dragons are four-clawed, above a base border of waves. Blue/green faint tinge to the body, and a six character mark under the base. Vase was purchased in the 1950s or 60s from an English dealer in the UK. The neck has a rounded-off edge, and possibly could have been cut down after damage. Quite thick porcelain to the neck, with finger ring ridges all the way down internally. On the external topmost ring of decoration, there is a feelable ring. Quite heavy porcelain, weighing 650 grams. Some pits to glaze under base around the mark as Chinese pots often have, from sand in the kiln. May be original, or may be early 20th century copy. I'm no expert here. Vase measures 20 cm high and about 12 cm diameter. No damage at all to the body, just the possible grinding of the neck as mentioned.
