I think you are on the right track. It is my guess that this radio was dropped at some point and the cabinet was damaged. Someone tried to repair it and didn't do a very good job. That would account for the broken corner and the misaligned base. The best thing is that wood can almost always be repaired.

It's impossible to tell from photos just how tight that joint is held together. If there is any looseness, you might be able to pop it down by laying a hard, straight edge across the bottom of the trim, from one side to the other, then use a clamp to press the bottom down. Glue it and you will be set. Keep your ears open for any cracking sounds and go very slow on tightening the clamp. Any cracking, then stop.
