Great Greatma's Doll

I just received my great grandmother's doll and I can't identify her. I believe it is a turn of the century doll.

She is 10.5" inches tall with a porcelain head and a wooden ball joint body covered in what looks like composition.

She has an open mouth with four teeth. Her eyes are made of glass that used to open and close (they are now in a fixed position). The markings on the back of the head are "1.H.K.3/0".

Can someone identify what the numbers/letters mean?

Thanks for any help you can offer!
