Small earthenware bowl with nice glaze and no markings.

Thanks for looking,

It looks a bit like Bay Keramik glaze.

Could be. I'd thought it was something like Bretby but W German is definitely a possibility.

It doesn't look like Bretby to me to be honest, different colours and glaze. I would expect most Bretby pieces to be marked as well and possibly not being that small   

I wouldn't say Bretby either. Bay sounds logical.

Thanks Redware. Bay it is.
