porcelain mark on lady figurine

I received a figurine from my grandmother before her passing. I'm curious to know more about this piece. It is a lady wearing a bonnet, holding a parrot in her arm. On the back is a mark that looks like a capital letter S with some marks around it in a circle. Also next to that in a circle is the letters DEP. There are also some numbers stamped underneath these markings but I cannot make them out. Any information on this would be appreciated. (I can post pictures if necessary)
