WWI Austrian warbond poster font


I am looking for a font matching the type on this poster. It's a WWI austro-hungarian warbond poster.


AFAIK this Art Nouveau lettering has not been made into a font.
I did find a font with very similar curls but it is too heavy and has serifs. Here is Svetoslav Simov's Rolka http://www.myfonts.com/fonts/font-fabric/rolka/

Thanks for your response! :-)
