History of the Original Enterprise Filming Model

Came across these videos of the original filming model of the Enterprise from
TOS and its journey from Desilu Studios to the Smithsonian Museum and all the
restorations it's been through over the years.
Detailed examination of the latest restoration carried out by a team of
Hollywood SFX folks, many of whom worked on TNG and the various movies

The entire history of the model's various restorations and where it's been on
display over the years.

And for fun, here's a guy unboxing a new 1/350-scale model of the TOS
Enterprise from Tomy and giving it a review. This thing is huge as models go.
Have to say some of the shots he took at the end of it in the dark where quite
nice.
