Bursley Ware - Rosemarie pattern. Any info?

Hi there,
I’m struggling to find any reference to this pattern given as ‘Rosemarie’ on the back of a set of demitasse cups, saucers, creamer and sugar.

I was interested to know the approx date and if it could be appropriated to a designer.

The blue is transfer print with a green hand painted wash and hand painted orange petals.

There are no other impressed marks, just what I assume is the decorators mark (possibly a B) as it is the same orange as the petals.

Any help much appreciated.

Thank you!
Jen

The Rhead book gives this mark as 1929.
There are elements of Frederick Rhead in the design,
but no record in the book for Rosemarie.

Thank you, that’s very helpful re date.
I can’t understand why there’s nothing on ‘Rosemarie’ could it have been a pattern that didn’t go into full production perhaps?

Woods made lots of named tableware patterns over decades.
This is just another of their named patterns.
Probably expensive to make, with some hand painting and gilding.
