Help....who made me?

I was in an op shop on Tuesday and saw a huge bowl... terracotta outside and this lovely glaze on the inside. It was behind the counter and after asking...I was told it's not for sale yet as it's got a backstamp so we need to find out who made it before we price it...
Well... to be honest it was huge.... where would I put it?
Then....   someone loves me lol.... I found this... much better size and more interesting with its scroll and shape.
But... does anyone know who the potter is?
It has 2 backstamps .... one on each end.
