CHEN Mingyuan 陈鸣远
Yixing Zisha Clay Walnut Teapot by CHEN Mingyuan of Qing Dynasty 陈鸣远核桃壶
Qing YiXing Zisha Clay Pumpkin Teapot by CHEN Mingyuan 陈鸣远东陵南瓜壶
Just confirmed this teapot has a great clay - It got refreshed completely after usage of just one day. Generally speaking, calligraphy is hard to imitate.
Comparison with the one from the book:
Similarity: shape and craftsmanship, clay, calligraphy
Difference: the one from the book has a more detailed handle, and a repaired knob.
