Our Fisher Price Jack in the Box– the crank turns but no music and it doesn’t pop up letting Jack out of the box. can that be fixed? If so how? Thank you

Info on this toy is slight. At about 7:40 on this video it shows a rubber belt. In my mind this would probably harden and crumble over age, but the video may give you some clues. https://www.youtube.com/watch?v=sbbDUEMR

I think in terms of display value opening it up and making it work will probably ruin the piece and not make it any more valuable then if it doesn’t work. You see what I’m saying? Sometimes it’s best to leave the old ones alone and just enjoy the look of them.
