and may I add my 50 cents worth?
Usually, and this bears careful watching, the label "wedg(e)wood" , indicates copies from Asian imports.
and this is where I love this research - "real " Wedgwood does not have the "e" after the "g". BUT there is a company in Britain long ago that used the W --- WITH the "e".
CAUTION: Not necessarily with Royal Stone China in conjunction. My conclusion, and I agree with DB, is that your W---ewood, is a late 20th century import.
