Walter of Wabash Table & Solid Cherry By Harden Chairs

I have an oval shaped, solid cherry wood dining table that is branded Walter of Wabash and also Frank S. Harden on the sliders.  I would describe the color as medium brown.  The table expands with two 10 inch leaf inserts.  I also have 3 side chairs and 1 arm chair that are branded Solid Cherry by Harden and the # 158 on the underside of the chairs. I have done some research and I believe they were made in the mid 20th century.  The set is sturdy and durable.  There are some scratches on both the table and chairs but overall in pretty good condition.  I would like to know the value of this set.  Any information would be appreciated.  Thanks.
