Well , after a battle on the lathe infinity focus is achieved.......however the war is not over as every now and then at infinity focus the mirror just clips the rear element.....focus a little closer and all is fine........so a couple of mm will be required to be removed from the rear element's housing, there is enough meat there fortunately.......will do that tomorrow!

Also note that that 85mm f1.5 Helios 40-2 is used on FF there. To get similar "extreme" swirl, you will need a focal reducer on APS-C mirrorless.
Also note that Dave purchased two 44-2 lenses, which are 58mm f2 lenses.
Yes, it's the 85mm F1.5.....................the bubble bokeh or however one describes it's effect is certainly a lot stronger than my 44-2 58mm F2 Helios which gives about a 1/3rd of the effect of the 85mm.
That lens though is rarer and commands a higher S/H price on ebay and so far I've yet to see one on my "Le Bon Coin" site here in France, ironically, as I said in an earlier post in this thread the Helios 85mm is now available new on ebay for 314 euros/£250 plus postage.......it looks very nice and is built like a tank (a T34) and "cocks a snook" price wise at some of the kick-start recent offerings.

The effect is pleasing though in the photo link you posted, similar to a fish-eye lens it's really for occasional use so buying cheap is the way to go, keeping my eye out at the flea market though.
Moving forward in time..
At the fair i pulled out the Helios 44-2!
6 seconds F16 ISO 50.
Nice. Shame about the sun stars
A few extra notes about these lenses:
-If you have the m39 version with a m42 conversion ring at the back, beware that if you put the ring on backwards, the lens may mount incorrectly on to the camera. In this case, the numbers that should be facing you will be towards the side of the camera. Simply check the m39-m42 adapter instead of going through other things first.
-Some of the older versions have a rear group that screws to the main assembly that you can reach without disassembling the lens. You can control infinity focus by adjusting how far that group goes in/out. You may even be able to get infinity focus on Nikons without any major modifications. Have no idea about the optical performance though.
-Just like the test posted on the previous page, Helios 44 models can reach a more than adequate level of sharpness when stopped down. Don't disregard them for soft focus, one trick ponies.
-Later versions with click apertures are really easy to modify into clickless aperture. Just disassemble the lens and remove the small metal ball. You don't even touch the optical assembly.
