The small pin you can see at the front edge of the lock is indeed an anti drill pin.
This pin has no effect on the picking of the cylinder as it only serves to stop it from being drilled and does not protrude into the keyway.
On some cylinders some of the actual pins are hardened as well but you would not be able to distinguish these just by looking at the bottom edge of the cylinder.
Hope this helps.
Indeed it does answer most of my questions.
Thank you Tattoo Guy

So..to sum up (if there would be anyone, who would try to find it):
I. If there is a one differently marked pin on the bottom of the lock, from the key-side - it does mark the anti-drill pin.
II. The marked anti-drill (fortified) pin does not go into the keyway, so in effect - it provides no extra security against picking.
III. Some normal pins (in the higher-class locks?) may be made of a stronger alloy to give extra security against drilling, but there are no distinguishing marks to tell us if those pins are actually in the lock one is up against.
IV. Some different brands of locks have other security measures against drilling, like for example: ISEO plugs have a small groove (don't really understand the purpose...but hey! What you say, I accept

(Just to add, in case somebody was wondering: i really am against drilling locks. The only purpose i'm gathering this information lays in the sole purpose of finding more information about security overally, so db don't be mad about this whole drilling thing

Not to worry. I have my exams, starting monday, and lasting untill feb.8th. And besides - something's wrong with my dremel, so i can't make the picks i've designed for the M-T-L untill i get it fixed.
