Large bowl signed NOLAN - Probably Graham Nolan rather than Wendy Nolan

Anyone have any ideas who this can be, is it possibly Helen Nolan?? can't find her mark to verify it though

Could be by Wendy Nolan. Colour of clay looks right, and blue-and-yellow-on-white glazes look right, but I've only ever seen her signature incised before, not written in glaze.

Or possibly Graham Nolan from Hampshire. Come across that CP mark with the dots on pieces stamped GN, and one had a handwritten ‘Graham’ , but it does also look like Wendy Nolan’s handwriting.

Heavy 12” across casserole, wax resist decoration in browns and light brown.
Marked Nolan and possibly a CP mark.
The only Nolan I could find was Wendy Nolan. Would this be an early one of hers?

Its a bit of a mystery as there's a Graham Nolan, Ringwood Pottery, Hampshire who has a label, and there's a mystery GN with a stamp, and a Wendy Nolan who signs her work. Both the mystery GN and Wendy use a similar symbol, so I think they must be husband and wife, although Graham was in Hampshire and Wendy in Hereford so maybe ex-partners?

Just found the pot again and found this post- thanks Naomi.
