Antique Highboy or Tallboy

A friend of mine's father gave me this as well as some other pieces for taking care of his beloved dog when he had to move into a nursing home. It looks great in my office and has really got me curious. I have spent a lot of time trying to find information about it but have not been able to find one exactly like this one. Everyone says it's very old. My grandfather says it may be pre-civil war. I would appreciate any information anyone may have.
