It's been a long time since I've watched a restoration video... these are best at 2 times regular play back speed, you can select that in the video settings

I found another I wanted to show you, but the people that made it won't let it be seen unless you watch it on You Tube:  https://youtu.be/h0ww4rRjivA

it's satisfying to see these, but let them run at 2x speed so it's not so time consuming, bead blasting is dull to watch

This last video channel, The Fabrik, has a LOT of these tin toys getting restored,
