"ROYAL HEIDEN" above a crown on top of "FINE CHINA" and "BAVARIA-GERMANY".
Not only is this mark not mentioned in any reference book, but it also contains the term "HEIDEN". This does not make sense in marks based on the German language, as it is the plural form of either "heath" or "heathen", making its use in this form sound rather foolish. What makes this even more puzzling is that there is a mark from former Czechoslovakia which uses "ROYAL HEIDEN", please have a look at M090613.
