Grandfather Clock

The clock is a family heirloom.  I am trying to get an idea of its age and approximate value.  I know it was in my great grandfather's home in the early 1900s.  My mother, however, insists that it was already an antique at that time.  The clock is powered by weights hanging from chains inside the body.  I apologize for the poor quality of the photos.  They are scans of pictures my mother took.
