I am no real guru on them but the bottom wood the draws look to have been repaired before as there is a vertical dowel through both of them plus the left ones chipped besides they look mushed and the back end of the bottom wood well that tells the whole story shagged? Get a NOS or good 2nd hand and fit it up plenty of info on this site on how to's.
I'm with Ron on this one, so much damage and old repairs, I would fit a replacement and set about the fun and games of bedding.
As said, plenty of correct 'how to' resources on here to absorb....
