This is a Royal Sabre serial #SB 9244894 which puts this in the mid 1970's.  The machine is exceptionally clean, but the main spring is weak.  What you see in the video is about as far as she will get across the page without help.  It is the only issue.  I've always liked this typewriter in this color, just because it's different than what is normally out there.  The typewriter comes with a new ribbon and is ready to go.  The item is cross posted.
