Value of Wooden Chair?

You will need a better description, as it is not possible to tell very much about your chair from the pictures presented.
Is this a rocking chair with broken rocker boards?
Is the seating leather?
What is the condition of the leather?
You will need to provide answers to these questions and also provide any provenance that is available about the history of the chair.

I have not found any chair or rocking chair that has this type of cushion, so it may be best to seek help from the company.
This is a Facebook page that has email addresses for the company and also a manager.
Try asking them for help, as they will know what chair you have by the number 574.
They should be able to provide the information you're looking for.
The condition of the chair does not look very good, so that will lower the value considerably.

These links have information about the company that is interesting but not too informative on age; the only thing that I see is your chair was made after 1919 but probably in the 30s.
