1940's/50's Mount Airy Chair Company Dining Room Suite

This dining room has been in my family for over 50 years.  My grandfather was a fine furniture maker, but he purchased this suite from the Mount Airy Chair Company.  I believe it is cherry wood, very ornate, a solid set.  The table has one leaf.  There are some chips and knicks, and the keys are missing for the locks on the China Cabinet doors.  My mother just passed away at age 94, and we are trying to determining the value of this set.    Thanks for any information you can provide!
