I have a Winchendon drop leaf table , and wonder what is its value.?

I am the original owner of this Paul McCobb designed WInchendon company blonde birchwood drop leaf table. My parents bought it new in the early 1950's. It has the company label on the bottom with production number 1524 stamped. I would appreciate any inquiries as to its worth. I have a general opinion from furniture store locally and some others at $750. in unrefinished condition. thanks
