Trying to FIX 3x 1970s Pull Cord Talking Toys

Hi, in this 'trying to fix' video I attempt to fix 3 talking toys from the 1970s, a Womble, Rupert the Bear and Mickey Mouse.
These pull cord toys were made in the UK by Burbank Toys. The voice box inside them is a nice little piece of engineering which appeared in numerous talking toys from that era.
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.
Spoiler Alert....

Rupert is now back home with the original owner where he belongs :-)
Many thanks, Vince.
