A large dish, potter unknown.

A large porcelain dish with as clear a backstamp as you could wish to see. Any help with the maker much appreciated. I have been through my book and cannot see anything similar. On that subject, does anyone know of a more conclusive book than the one by Yates & Fournier ? I find it inconsistent and a little lacking in some respects.

Thank you for the feedback, though I do not think this is Quimper.
The collection it came from was from someone that collected British studio pottery. And besides, just doesn't feel or look like Quimper, but thanks anyway.
