Pottery info needed - please assist

I am looking to see if anyone knows of a set of pottery that I have required or maybe even tell me if it is worth much. It is a piece by 'Gray's pottery' by the 'Johnson Bros' and also has the writing 'Rosedawn inscribed. If anyone knows anything about this particular pottery or knows a website which might help out I'd be grateful?

For God's sake, a Google search for 'Gray's pottery' produced 'about 1710' results !

It certainly will, but expect the OP to come back telling you their internet career credentials and how they already *did* check all of those links. It's a good thing you didn't ask questions about their item description, as they'd use that to insult you, also
