Help identifying porcelain bust sculpture

I have this lovely porcelain art nouveau bust. Very similar to Eduard Stellmacher but only numbered (double line under 6) which is common with Amphora busts and Stellmacher busts but no stamp? I cannot find any matches online.

 

I can post more pics if needed

 

I doubt I could add anything other than it looks Austrian/Bohemian and turn of the 20th c. That said, a photo of marks is helpful often. And when you upload photos, hit "full image" so that it appears like Debora did in the above post. Your bust is a quality piece, so maybe no mark because there wasn't room?

 

Thank you!! That is still helpful
