vintage Korea celedon green vase, meiping shape w/ cranes design crackle glaze ceramic

Lovely vintage celedon green crackle glaze vase with cranes, about 6" tall. Marked as shown, I was told this is Korean pottery, mid or late 20th century.

The shape is the meiping style, commonly used for flowering branches. It's clean inside and out, I don't believe it was ever used for flowers. No chips or cracks.
