dining set

Seller claims its made by Baker Knapp & Tubbs but doesn't know when it was made (belonged to her parents).

Also the side table seems to be a different manufacture that goes well with the rest of the set - any ideas on who made?

What is a set like this worth? It looks to be in excellent condition. I don't want to lowball them but I want to make sure its worth their asking price.
