Zwiesel with IE please, "zweisel" makes no sense @ all.
"Kingfisher" as a colour only refers to Whitefriar's - it does not travel well. Whitefriar's is a local celebrity only.
and: re size, weight, finish, use of colour and definition your piece is quite typical for Zwiesel (who also produced for WMF) - just this specific model has not been identified.
