Interesting (Primitive?) Japanese Kyusu Teapot

Here is an interesting Japanese Kyusu form of teapot or herb cooking pot from an old San Diego estate. I have been unable to identify as to the where and when and who.

The pot is 7" at its widest, and 6-1/4" from base to rim.

It seems to me to be unusual in several ways: 1st, its burnt honey color of outer glaze coming to 1" from the base. 2nd, its courseness inside and out. 3rd, the pot itself was NOT made as one piece on a potters wheel, but was constructed in 2 pieces; the top half of the pot is JOINED to the bottom half and it appears the top half was set upon the bottom half and the outside edges rubbed into each other likely by a stick or paddle at the midpoint, 4th, its handle and spout are both pointing in the same direction instead of angled to each other. I really don't know what to think about it, as I have found nothing similarly constructed on internet searches. My only guess is that it is an older one of which very few survived as teapots in Japan had much use with low survival rates.
