1920's Jenny Lind 4 poster Bed

I have the full size bed, which includes the headboard, footboards, bed foot rails. It is stamped with the Wheeler-Okell on the back of the headboard and footboard towards the bottom with the number of 633. I also have the matching night stand, dresser with swinging mirror. I received this as a gift from my grandmother in 1988. The history of the bed, was that my grandmother's mother bought her the bed for her wedding gift. My grandparents lived on a farm, their house caught fire while my grandfather will tilling. When he looked at their home he saw smoke rising he ran... When he got to the house my grandmother was busy pulling the bedroom furniture out of the house! She has always cleaned the furniture with lemon oil, as I still do to this day. I am just looking to get a estimate of its value.
