 I don't know how rare model 38-5s are but it may be worth holding out for another cabinet. You could disassemble the cabinet to repair it, sometimes it is necessary to do that, but it is a long process so it's best to make lots of notes and or take lots of pictures whilst you are dismantling it. I would not even suggest doing this unless it's a rare or valuable model.   There is one potential problem that I can see, one of the missing pieces of veneer is broken across the grain on the curved pilaster (side column), on a flat piece like a cabinet side this isn't a big deal but on a curve the veneer is under tension so the two ends might pop up again even after they are glued down, plus the crack will always show. In cases like this it may be easier just to make a parallel joint along the grain and replace that section of the veneer with a longer strip.
