Antique Dining Room Set

Antique dining room set.  It  includes a table that extends on both ends (from 61" to 104"), a buffet, and 2 piece hutch.  We have 2 original chairs and some pieces of the others. It is hand carved. We bought it in the mid 1970's and the lady we bought it from said it was over 75 years old at that time.  One drawer in the buffet has a wood burned trade mark  (see picture) that sayd "LIMBERT FURNITURE TRADE MARK BY VAN RAALTE CRAFTSMEN GRAND RAPIDS & HOLLAND, MICH."  I have included several other pictures also.  We are planning to sell and would like to know the value.
