Shino ware teapot by Rick Hintze, 1980s

This teapot is about 6" high x 7" spout to handle x 4.5" minus same. It is signed with "rh" in a square on the body of the pot. The finish is Shino ware, a Japanese glaze

No wear or damage, $3 GW find today. I did not notice until after posting my images that I had not put the lid on properly. It actually fits very well, flush against the body of the pot. What appears to be a chip on the base in the first image is a flaw in the glaze.

This is one of the best Shino ware finishes that I have seen, but I am not sure that it was made in Japan. The shape is non-traditional for a Japanese kyusu and it is a bit large.

Update:

At first, I thought this was the work of Canadian potter Robin Hopper, but when I contacted his partner, she said RH only put his mark in a circle and only on the unglazed part of the piece at the bottom. He also typically included a stamped impression that said "Canada" or the name of their studio. After revisiting my search I concluded that this pot was made by Wisconsin potter, Rick Hintze, which he confirmed. He dated it to the late 1980s.
