Vintage Japanese Clay Teapot Kyusu Side Handle Pottery Ceramic Stamped

I believe this is a Japanese clay teapot. It has orange / rust colored spots in the glaze.
It has a small maker's stamp/seal on the body.
It has a metal mesh strainer inside.
Measurements are shown in the photos.
Good, used condition. There is a small chip to the end/edge of the handle. The inside shows residue and signs of use. Please examine photos for a better look at the condition.
