Mart thanks for looking, I know the Garden is Priority!
Ipcress, I was thinking it was possibly Adams also after doing some research, but, like you, the quality of the pate sur pate and the impressed numbers had me wondering and thinking it might be Wedgwood, just was not certain... I just keep feeling it's old Wedgwood, look, feel, quality, although I have not seen and handled too many old jasper dip pieces... Perhaps, like you say, an email to the Wedgwood museum would be the next step to be sure.
Thanks!
Kevin
