Antique Chair with Swivel Rocker

I purchased this chair at our local Salvation Army for $75.00. I fell in love with it when I saw it. Very well built on a swivel rocker. If anyone has seen a chair like this before, please tell me what era it's from. I had an antique dealer look at it and he had not seen one like it but said it was a very well made piece that someone invested a lot of time and money into making it. Probably around the mid 1900's. Any input would be appreciated.
