Welcome Bob
That would be interesting.
Honestly though after 10 or 12 blades the iris is round enough.
Maybe I am wrong but more should not improve highlights and could be more of an issue if in need of maintainnce.
I think the Tair 11a I got from Richard has 20blades

I agree. And it's not always about the number of blades. Volna-9 has only six blades but they are shaped to make perfecty round aperture at f/16. |

This is perhaps slightly aside of the blade count list, but I'm always 'shaping' my understanding of photography.
I'd be curious what you folk each feel is the magic number (of blades)?
I'll admit I'm a fan of blatant polygons. I rather enjoy the 5 and 6 blade pentagonal and hexagonal shapes in my highlights if I'm stopping down, but they seem out of fashion in todays world from a marketing standpoint. I often notice in movie bokeh however, polygonal is the norm and I wonder why still cameras are different? I theorize, but I don't know.
I've often thought being able to choose aperture shape would be an interesting step. Not just with the lensbaby, but on a 'serious' lens. Perhaps a switch that would disengage half the blades, so the aperture could be a 10 or 5 blade design for example. Anyways... I find the topic interesting - sorry for the ramble, heh!
ps - @ BobF - Pentax, in their literature on the upcoming DA*55/1.4 make some bold claims of the magic their curved blades will weave over 'creamy' bokeh. I giggle at the ability of the marketing dept to conjure up such things, but the fact that it will have curved blades may be of interest.

i guess the design criteria must consider the performance with an automatic diaphram, friction et. al.. preset makes it much easier to design a multiblade system.. curved clearly is desirable to minimize the number of blades for a circularly symmetric aperture

The cited website [ http://m42.artlimited.net/site_lenses.php ] returns 404 NOT FOUND. Darn. Anyway, following is my own 10+ iris index (with mounts in parentheses).
From my current accumulation -- focusing lenses:
Isco Westron (M42) 35/2.8 -- 13 blades
Enna Sandmar (Argus) 35/4.5 -- 10
CZJ Tessar (Exakta) 50/2.8 -- 12
Jupiter-9 (M39) 85/2 -- 15 blades
Meyer Trioplan (M42) 100/2.8 -- 15
Enna Tele-Sandmar (Argus) 100/4.5 -- 10
Opticam (T2) 135/2.8 -- 10 blades
Enna Tele-Ennalyt (M42) 135/3.5 -- 13
Hanimar Preset (M42) 135/3.5 -- 13
Jupiter-11 (M39) 135/4 -- 11 blades
Schacht Albinar (Exakta) 135/4.5 -- 18
Meyer Telemegor (M42) 180/5.5 -- 15
Vivitar Tele (T2) 200/3.5 -- 18 blades
Pentax Tele-Takumar (M42) 200/5.6 -- 10
Enna Tele-Ennalyt (M42) 240/4.5 -- 10
Spiratone Telephoto (T2) 400/5.6 -- 13
Non-focusing lenses (ENlarger or MF-folder or LF):
Vega-11U (L39-EN) 50/2.8 -- 10 blades
Zeiss Tessar (33mm MF) 80/2.8 -- 12
Agfa Apotar (1-inch MF) 85/4.5 -- 10
Apos Elgeet (29mm EN) 90/4.5 -- 15
Novoflex Noflexar (M42-EN) 105/3.5 -- 15
Industar-100U (L39-EN) 110/4 -- 10 blades
Ilex Solar Anastigmat (L39-EN) 140/4.5 -- 15
Wollensak Enlarging Raptar (EN) 162/4.5 -- 15
Kodak-Rochester Optical (33mm MF) 162/5.6 -- 10
Gundlach Turner-Reich Anast. (65mm LF) 300/7 -- 15
I should mention that bokeh results from factors other than iris blade count and shape. My Schneider Betavaron 50-125mm enlarger zoom has only 5 blades forming a very star-shaped aperture; but put on extension for non-macro shooting, its bokeh is EXTREMELY smooth and creamy. Maybe the kilo of glass in there has something to do with that, eh?
I'll also note that mount can be significant. This is expecially noticeable with the CZJ Tessar 50/2.8. My Exakta-mount version has 12 blades, while my M42 version has only 5 blades. And cost doesn't necessarily have much to do with blade count. My cheap Hanimar Preset (M42) long 135/3.5 currently sells BIN-NIB on eBay for around US$20, yet has 13 blades. And they work!!

There's the All Photo Lenses database here:
http://allphotolenses.com/lenses.html
This does have information on the number of blades in many of the lenses, but unfortunately the field doesn't seem to be searchable.
