Thanks for the answers, especially yoyomaoz! Funny how the eBay link has pretty much the same setup I have with black extension tube, even though I had not seen that one while making my own setup for the lens.
I got the lens from my now deceased grandpa, whom I asked few years ago if he has old cameras hidden somewhere that I could use. He said no, and that he has not owned nothing but "just basic cameras". That probably ment there were no SLR's. But he sure was keen to film video. I remember he had Super-VHS camera, so now I'm thinking that maybe this is a lens for like 8mm homefilm camera?
By the way, I once had success making dia projector lens Will Wetzlar Maginon 85mm f2.8 focus to infiny. It only focused very close when adapted. All it needed was me to glue the lens into Contax/ Yashica adapter, and then attach it to my Vivitar 2x Macro Focusing Teleconverter. Teleconverter has it's own focusing ring, so with that I was able to make it into a 170mm f/5.6 macrolens that focuses to where I want. Image quality wasn't very good when focused to infinity, but the rendering of the lens stayed pretty much the same.
Here's a better photo (I hope) from the mount measured. It looks like the protruding element is exactly 20mm long + the rear lens element that moves when focusing. And yes, the screw mount on this lens is M42, not M39. Sorry for a photo with such distortion on the lens, it's taken with my phone.
