Lidded large cup/soup bowl

Unmarked, 14cm diameter, from Oxfam Chelsea.

Any ideas? thanks for looking

Does the lid match ? , it looks a bit out of sorts .

I have wondered that. They came together. The glaze and clay are different. Doesn't fit very well. So...probably not.

But the cup needs a lid or else it is somehow too big and it's clearly a functional object.

A lot of soup bowls come without lids. I don't think its a prerequisite.

it does look better without the lid , but no idea of maker   

Reminds me of Tremar, but I think the bottom's wrong.
