Earthenware Vase identity please! CW or CM mark? - Jonathan Williams

Having had this one on the back of a shelf in the garage, Blow me If I can remember who it is buy! I would be grateful if someone could remind me. Anybody else have this problem when unearthing pieces long in storage?

I think it’s a CM mark. I’ve seen it before but not finding it atm

Found it in the Marks book. By Jonathan (Jon) Williams, potting in Bath in the 90s, making terracotta garden pots etc

Thank you very much Naomi.
