It does look like the Davidson one, doesn't it? Angela, can you count how many panels there are on yours round the edge please? The catalogue image shows 20 panels, and the tray size in inches is 13 x 8 which equals the cm you both state above.
As to the rosen lidded bowl, the catalogue just shows it as a dosen with a diameter of 13cm but I can't see any matching pieces for it... perhaps Pamela would know?
