Haven't seen one quite like this one. I'd guess '30s, '40s, or early '50s for age based on the design. I am puzzled that the rockers are pine, though. Rockers take the biggest part of the wear on a rocker, and maple would be a much better choice.
I like its looks. You might try looking at High Point, North Carolina for more information -- that's the other major area for furniture building in the US. Some of my ancestors were working wood in that area in the early 1800s.
