The set I have seems to deviate from every description I've read about the Willow pattern:- he bridge is to the right, the pagoda on the left, there are only two figures on the bridge and there is no boat and no doves.
The pieces are all marked with Wedgwood Etrutria England (stamped), imprinted with WEDGWOOD and marked 3ER, which I understand dates them as 1915. There is a further mark which has been obscured by the glaze.
Can anyone help with further information on this pattern?
