If you look at the other patterns produced by Enoch Wedgwood, none of them are anything like this bowl. Is it possible that some undecorated items were sold to another firm [or even an individual] and they decorated them in the style of Clarice Cliff?
The way to get a definite answer could be to send some photos to the Wedgwood Museum as it says on their contact page that they will help with identification of items. Their email is archives@wedgwoodmuseum.com.
