Stevens 107b

This is just a short vid showing the Stevens 107b broken down into its component parts.
Tried to create before and after flick of this restoration in iMovie. Can't do it.
Tried to upload still pics of before and after to KZbin. Can't do it.
If I am living in the 21st Century...why are Apple and KZbin still in the 19th century for flexibility and support?
I tag this as safe for kids....but that means no one can comment. So I need to make an adult film about the Stevens 107b before I can get any feedback or help? Ugh.
