I have a old office desk that I am pretty sure is an antique and would like to know if anyone can tell me more about it, such as who made it, how old is it, how much it is worth, and what kind of wood is it made of? Any information would help. It has 3 drawers on one side that has the brass handles, the middle drawer underneath the center of the desk takes the old skeleton key to open it, and on the left side of the desk it has a cabinet door also with brass handle and when you open it it has a foldable wood shelf inside. And on the top of the desk it has leather embedded in it.
