Unfortunately I don’t know much about the helicoid (the focusing part), it was already installed when I bought it from the seller on eBay. Though the helicoid has a very worn “Made in USSR” on the side.
But the last part that adapts the helicoid to Micro 4/3 is a pretty cheap and easy thing to get on Amazon or eBay as long as you know the mount you’re adapting from. In this case it was also installed by the seller in my case. Though I have bought those adapters (m39 and m42 to Micro 4/3) for other lenses I have.
I’ve shared a collection of stuff that I can share right now in another comment here highlighting some of the pics it can take, and a cool example of how it can focus on objects behind what’s in front of the lens.
