Unknown Rocking Chair

I repair, refinish, buy and sell furinture. I found this rocking chair at a local auction and picked it up for next to nothing. I have seen a lot of different styles of chairs, but never one quite like this one. I can tell by the way it's made, and the condition of the wood that it is quite old. It is mahogany, and very sturdy. Just wondering if anyone has seen a chair like this one before and could give me any info about it. Thanks.
