Found these at an Estate sell. Beautiful, high quality stoneware Foo Dog statues. Maybe Shiwan pottery circa 1920?

I think these are Shiwan, but if anyone else has an idea about them please chime in. I'm pretty sure they are 1920's. They are both in EXCELLENT condition. I have seen similar types, but not of this quality and with this particular glaze. It might be a Jun glaze. They are 17 inches tall. I adore them and would love any input to their origins. They have a fusan stamp which I believe is unusual . I need to get better photos, but I am having camera issues at the moment.
