Heritage Henredon Furniture

 This is a piece my grandmother left me when she passed away. She used it as a television stand, but we aren't sure exactly what it is. It has two doors on either side that are lockable, unfortunately we don't have the keys.  The top slides out on either side to extend the space. It has a stamp on the inside that says "Heritage Henredon."  We are mainly interested in what it was used for for or how it was marketed. One of our guesses is that it was for entertainment or a bar. We are also curious about its age. Guessing late 60's or early 70's.

Thank you for any help you can provide.
