Welcome to the forum. Nice looking box. You'll find many here to help you with their helpful advice. Take what you can apart, clean it, polish it, scuff it, paint it. You'll have many hours into restoring that box. Take your time , do it right.
Please keep us tool box junkies updated and take lots of pictures. We do love pics. Any helpful advice from me ( I'm not a expert but I have restored many of boxes ) just pm me. My wife say's that I have a problem. I ask, and what might that be? All those damn tool boxes you have in the garage and basement.
I'm an addict. One box at a time. Enjoy, Johnny Generic.
