Trying to FIX: RARE J.Swedlin Voice Box (DONALD DUCK Pull Cord Toy)

Hi, this 'trying to fix' video shows me attempting to fix a rare vintage voice box from a J.Swedlin Walt Disney Donald Duck Pull Cord toy.
Sorry, there is no quick version on this video.
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince.
