Very nice Cornish bowl (not Christine Bull)

I wondered if anyone could help to identify the maker? This was given to me as a present in about 1990. It was sourcrd by an artist in Cambridge and may have come from Cornwall. I am not sure about this. I think the artist who made it is female. It is rather beautiful and I should have paid more attention at the time.

It might be David Frith, but the mark is very small in the pic,
any chance of a close-up of the mark?

It is difficult to make out. I keep seeing it in different ways.

Looks like a dp mark to me

Thank you. Does anyone have an idea of who DP might be - assuming this is the mark?

Christine Bull has a similar mark in the Marks book but I don’t have an example of it. Best to contact her to verify it. email address: chris@meadowcroft-pottery.co.uk . She’s at Meadowcroft Pottery, Askett lane, Askett, Princes Risborough, Bucks HP27 9LU

Thanks for the suggestion. I had already emailed Christine but she doesn't recognise it. It is tantalising..... It's a nice piece and the artist who chose it knew what she was doing.
