Makers mark question for Austrian art nouveau silver

I have acquired this small box which is hallmarked for Austria, Vienna, post 1867. From the design it has to be around 1900 I would think. It’s exceptional quality with a diamond sun and gold rays in a silver setting on mother of pearl. Does anyone know the makers mark? It’s too small to photo but is A.F (maybe a P or E) inside an oval that is indented at one end. Thank you Also can someone please let me know how I can “file” this under “Makers Mark” questions and not “Photographing silver” Thanks
