Identification of a pendant, Patron of Slovakia

[Uncharger]

Found a silver, gold-plated pendant of a virgin Mary variant - patron of Slovakia.
I believe the FS belongs to one of many Austrian silversmiths with such initials. The mark of 5 in a triangle eludes me completely, most probably missing a chunk of it.
Anyone could point me in the right direction?
Thank you
