Office desk with piano stool

This is an old office desk as used by myself and my father, the latter from the early 1900's. I am not sure of its exact age. There are 9 drawers. Each has a small brass knob. I am selling it with the piano stool shown in the other photo since this was used with the desk and fits neatly under it when not in use. The stool has a compartment which is under the hinged seat. Condition of both items is good considering the age, and the desk would come up well with care. The piano stool could do with the leather insert replaced.
