Really interesting. Thanks for posting up the link!
For those who might be interested in the history of plastic scale modeling, this same guy (“Max,” I suppose) has over 100 (!) short vids on the history of various scale model companies that are very entertaining and enlightening. Most are only 5-7 minutes long, so they make for a quick little video break. You could easily create a “plastic scale modeling” family tree to diagram the history from the information he provides.
