Details:

Overall should be fine its in great shape for what it is. One power light don't seem to turn on but its working bulb may be out. Around the fuse, end pieces is a little broken on both sides, but they still good and everything's fine. Or things are just not fully connected for the power yet and testing part.

Look to pics for details and such see yourself Ty: Looks be in great shape overall the age: Normal wear like scratches, scuffs, fading, etc Tested all seems order.
