I am looking for a Viennese silversmith maker's mark „S.G in the two-pass“
Two examples:
1. silver hallmark: Republik Österreich ab 1922,
Hoopoe head 2= (silver fineness .900),
Austria Assay City Letter W = Wien

2. silver hallmark: Republik Österreich ab 1922
Wing Import Mark 2= (silver fineness .900)
Austria Assay City Letter W = Wien

It is possible that this is the maker's mark of Simon Grünwald???
Does anyone know the maker's mark “ S.G in the two-pass“???
Any help would be greatly appreciated. Thank you!
