Roll top desk

This desk belong to my mother's father, my grandfather. She died at 86 this year ,  she was born in 1927, and was the baby of seven children. I don't really know when my grandpa got this desk but it was in their house forever.  There is drawers where there are'nt any drawers in the picture they were just packed in another car for moving the desk that day.   I would say the desk could've been may be around 1930s or 40s, but I don't really know.
