From the Kolarivision list, the old DA 18-55 AL II kit lens works for me with a converted Pentax K-r :

There were 2 special lenses in M42 for UV and IR. The Ultra Achromatic Takumar 85mm F4.5 and the Ultra Achromatic Takumar 300mm F5.6. Both had special filters available for IR work. Where you would ever find either of them is anyone's guess.
I drifted away from there because they only seemed to want to talk about lenses with German names...
