I do not have history on this piece. It was purchased from a auction and given to me over 18 years ago. It is very large "Cali King size". One of the support slats had split a long time ago and would need repaired. Mattress slats are all cut different and have warping. Each one fits into a specific location, possible hand cut. Some spall wood pieces that the hardware screws into have loosened or split. I am looking for help in identifying this piece including what it is, age and value range.
