@@riton4770 thanks for your comment! I don't have this lens anymore but from memory, it works pretty much the same way as most other vintage lenses. Once you have access to the rear lens group (as per my video) then the metal casing just screws open. Make sure to track the orientation of each lens as they are very easy to swap around and you'll end up with blurry photos. Also, ensure that you have lens cleaning materials and work on a dust-free space. It's very easy to make the lens dirtier than it was before. Hope this helps!
