Working with Mamiya-Sekor C 1:2.8 f=80mm Sticky aperture blades and Stiff focus ring PART 2

In this video, that is PART 2, I will show how to work with the Mamiya-Sekor C 1:2.8 f=80mm lens. I show how you assemble the aperture assembly with the aperture blades and adjusted to correct setting, then how to re-grease the focus assembly and put it back in again so it works correct again. I make some errors in the process during assemble the
focus helicoids, but corrected them again so the lens came back to life and everything is working proper.
