how to repair old wooden veneer?

Answer 1

It depends on if it's a chunk out of it or it's warped. The key word is "OLD" how old? Like antique old?
Just navigate this web site and it will give you easy reference on what to do. It will be a whole lot easier than someone trying to explain it, since we don't know the exact problem.
Good Luck
