Three very old bowls

I found these three old bowls today in a thrift store. I thought they were french at first - the decoration looks alot like some Sansome i've seen. But the undersides feel very Chinese. They feel and look just like my Kraakware bowls - same fritting and chattering [which i couldn't capture in my photos. There's a molded design in the rims too, but also difficult to show. Any info appreciated!
