Large Studio Pottery Lamp Base BD mark - Beryl Debney

The glaze is gunmetal grey with a relief pattern overlaying it - grey with a green hue. There is a clear mark BD. I believe this is a 70s or 80s style but just a hunch. Any information on the potter much appreciated. I wondered about Bridget Drakeford but doesnt look her current style and the initials don't look like hers.

There's a Scottish potter "in the book" that used a BD from 1975-88 called Barbara Davidson. I'm not familiar with her work but it states she made lamp bases, so maybe a possibility?

Thank you very much once again for your kind advice. regards

I think it could be Beryl Debney, Yoxford Pottery
