MIR-1 Full Lens Disassembly and Service Guide

My name is Li and I take photo for fun. I recently bought a copy of the MIR-1, a vintage lens from the 1960s with an optical design based on the Carl Zeiss Flektogon. The lens came in good optical condition but not the best mechanical condition, so I decided perform a full mechanical service on the lens. In this video, I explain and show all the steps required to fully disassemble the MIR-1 and provide some advice about cleaning and lubricating this lens. The disassembly process is shown in full, without any cuts (but with a bit of fast forwarding). I also explain some of the steps in reassembling this lens which are not covered by other channels already. I really hope this is useful to those of you that own this lens as this video took me a lot of time to put together. I wish you the best of luck in servicing your own lens!
