Rockford Furniture and Chair

I have enclosed several pics of a dining set I recently obtained and would love to know the history and value of it. The person I got it from has had it sitting in their dining room for 20 plus years and never used it. They bought it in NY for $400.00. I do know that the company is dated from 1905 to 1928 when the plant was then destroyed by a tornado. It was later rebuilt under another name. I cannot pin point the exact year.
