This picture was taken with the Pentacon 135 Electric and my K10D recognized it as K or M lens

How did you determine K or M lens?

The camera only knows 2 things, whether the aperture pins are shorted or not shorted,

If pin 3 is open, it knows nothing, if pin 7 is open it knows M42 that is about it.

I didn't, the camera did. If you look at the EXIF data, you will see it says "K or M lens" and I didn't set it that way.
