So I went back and tried to take a close look of the bullet sizer in the video. It's only visible for moment, and its not very clear, but the aluminum base appears to have the same shape as the early model discussed in an earlier thread, and it seems to have the cast iron Pressure Screw Nut on top.

It's really amazing that these two very early Star machines were captured in motion pictures. Thanks for bringing this to our attention.
Now if we could just find some pictures of the Star Machine Works. (inside and outside) They must exist somewhere.
