New Idea 30A Sicklebar Mower Repairs - part 1 

I have this same mower. Could you make a video of the ball on the bar and where it clamps. The clamp on mine is popping off the ball and I think there is some sort of cinch part I am missing. Your video is the closest I have to figuring it out.

Any idea on year of this machine? I believe early to mid 50s but can't find any info

Where would you get parts for this old Sickle mower at
