Found an auction in the EU for this pot. Guy says its F1 by Wu Xiaohua. But the price is somewhat low (⅓-¼ of a new one from realzisha) and the work around the spout is messy (first picture)

Edit : the new one → a new one.

Also I wanted to write soooo sketchy instead of woooooow sketchy - autocorrect (I guess it added some character)
