Hi Jonathan,

Thank you for contacting Mearto with your appraisal inquiry.
No one has identified this potter though there are other pieces by his hand - in slightly different styles - that have come on the market in the last 10 years, all at a fairly modest value. If yours did not have a hole in the bottom it would be worth more...
Based on the photos and information provided, and subject to examination, this is:
