Obviously you mean "You can make your own aperture Iris", as an Iris is not a diaphragm!
Anyway, putting such a disk in front of the lens would'nt work as all it would do is cause huge vignetting...Any such disk must be fitted somwhere between the front and rear elements inside the lens.
I have a Helios 40 with no Iris (Its long story) and I have tried fitting black cardboard disks with various sized holes in them in place of the missing Iris blades and it works great.
You simply remove the front elements to gain access to the iris ring, push the disk into place and replace the front element.
Removing the front elements of his miltary version would be an identical process as its optically identical to the Helios 40 but as it never had an Iris built in he would need to taylor make the disk to fit inside the lens. |

I never thought of making diamond or other shaped holes in the disks...I agree it would be interesting to see the OOF results. |

I have checked several examples of this lens and have found that there are two different ones.
The newer version (higher serial numbers) has a matt finish and a smoother focussing ring (not so "agricultural").
My copy of the better version has a serial number starting with 931.
Here are a few images:

Does anybody know how to remove the tripod mount?
There are three small screws in the ring that points to the camera.
Is it possible to remove this ring, then, and remove the tripod collar?
Handling would be easier without it.

Yep, they both come off.
To remove the ring, you need to loosen or remove all three of those tiny screws. The ring is actually threaded onto the lens body with very fine threads, so you unscrew the ring to remove it. It might be a bit stiff, as the three set screws have chewed up the threads. 
Once the ring is off, you just loosen the big knob on the tripod collar and it slides right off the back.

1.5/85mm also exists with protruding back element. The later the version higher the possibility. I'd dare saying it's totally different lens design with much lower quality glass. You can also separate it by that bluish coating (compared to yellow Tomioka type calssic). Just ask the seller of the coloring - he will share that info more easily then to unscrew the lens...
Did anyone successfully used 1.2/85mm?

I have found it a quite useful lens.
Only I was missing 1/8000 s on my K20 at times.

What you call matt finish looks like a textured paint. Why is that one better? Does it have anything to do with having the name Cyclops as opposed to that other marking?

I think it is. What's the extra ring in front of the lens? A screw-in lens cap?

Is that philosophical paradox ? Anyway if you refer to flange then it's about where every other M42. I am pretty sure it's also easily adjustable.

Perhaps! 
I have one of the "bad" versions... and the answer is:

Okay, I either asked the question wrong or you guys are screwing with my head. My 28mm close focus hits infinity at about 10 feet; my 200mm at about 125 feet. Anytime I've tried to measure actual infinity, I've run out of room.
While we're at it, do you know the minimum focus distance of the Cyclops as well? I'm trying to suggest some distances to my friend who is holding my Cyclops so that I can see results of bokeh and focus depth. I'm too eager to wait until I have it. I'm very excited about the wide open (as if I had a choice) performance of the lens having no CA. I also may be playing with it some to determine if I can insert a fixed diaphragm at an ideal aperture - one that would provide the much needed depth while still maintaining the bokeh characteristics.
