Disassembling, cleaning, lubricating Helios 44M 58mm f2

Revisiting lens CLA again after 2 years, I wanted to document the cleaning and lubricating process in its entirety as a "proof of work". As there are plenty vintage lenses out there, I thought a full CLA would be a much better value added service and thus command a higher price tag than other units in the market. For anyone that is adventurous enough to take matters into their own hands, hopefully this will serve as a valuable guide.
