Help identify maker of large stoneware fish bowl

Hi there does anyone know the maker of this bowl. Had for years and have never found mark. Measures 39cms diameter. Thank you

Thank you for getting back to me. I see what you mean about the mark.

I was wondering if it could have any links to Cardew as there is a likeness in the mark there as well?

A link to Michael Cardew doesn't seem likely as the type of decoration isn't typical of Michael or any of the potters associated with him. Cardew did use stoneware and a big C as part of his mark but those are the only similarities.

Naomi is correct about Kevin de Choisy from the work of his that I've seen and as far as I am aware he has in recent years only used porcelain and earthenware. I'm not sure if he has ever used stoneware.

thank you studio-pots that will stop me going off piste down that route!   

Whoever's it is, it's a very nice piece.

thank you pot-bellied amateur i like it as well. Just wish I could find out who the potter is!! I think I will try and get a better picture of the mark as It looks like GTF to me rather than CDE and see if it jogs any ones memories. Fingers crossed!

Thank you NaomiM for helping to search it is much appreciated
