Hi. Hoping someone may be able to help id the maker and date of this green & blue vase. Found in Yorkshire it measures 17 cm tall x 14 cm across at the widest part (end of wing to end of wing) and weighs over 1.45 kg. Flat polished base. When I first picked it up my immediate thought was Czech and in particular Chribska but I cannot find anything similar. The Sanyu 'fantasy' range has some similar shapes but I can't find anything that matches the colours. Any help would be much appreciated.
