Anyone know who might have produced a 42mm screw-mount 12 bladed aperture 135mm f3.5 pre-set lens for Sears?
The mount is a 42mm screw attached by three set screws. These when undone reveal a simple 'neck' which takes the screws. A useful thing is that on the K10D where the 42m adapter means that the distance markings are not at '12 o'clock' the lens may be revolved ion its collar until they are! lol
Looks very like a Takumar pre-set from 60's vintage?
These are 50% crops from camera at f5.6 on a very dull day with slight breeze stirring plants... re-sized by half for forum.
Thanks
Doug

I did do a search both in-forum and in Google for sears and 135mm f3.5 and nothing came up.. then I found this post by accident - and that's 'my' lens.. 
I guess my putting the 'f' before the 3.5 meant that the post did not match my search criteria! Shows how important that 'f' is..

Who made yours? Hmm could be one of a number even Miranda who contracted with Soligor a lot.. I have seen Hoya lenses that look similar?

Sounds like a T-mount. 
If you leave the three set screws tight, you should be able to unscrew the "neck" as well, revealing a set of threads which are still 42mm, but a different thread pitch than the standard M42 mount.

Interesting... Would you mind taking a photo of the "neck" and possibly a measurement of the inner diameter of the mount? This mount type might be useful for lens adaptations.

That 'neck' part unscrews. The 'neck' ring and the camera mount ring together are a T2-mount adapter. Photos here: http://forum.mflenses.com/just-recd-spiratone-tc-2-8-135-and-soligor-2-8-28-presets-t25497.html

NO!!!
Please take a look at the link I referenced in my post. It's NOT a T mount at all, the 42mm fitting screws onto the lens body by means of three grub screws, and the neck does NOT unscrew and is NOT threaded with any form of 42mm screw, .75 or 1 pitch whatever..
Picture 'stolen' from the post I mentioned.. this is my lens... nothing apart from the silver collar can be removed and that is via the aforementioned grub screws...

Now I recall reading a history someplace, this lens mount was made for a brief period to garner some Tamron T-mount marketshare, shortly before the introduction of auto-diaphragm T2 lenses. Chiefly (only?) the popular 135mm focal length. I'll try to locate that history... The T2 mount design seems to have 'lifted' part of the design from this lens mount, no?
