Earlier this evening, I was going through some boxes still in the attic from our move a couple years ago. While looking for a book, I came across a master no. 646 padlock: http://www.masterlock.com/cgi-bin/produ ... late=style
Now, I had no idea as to what the combination was, so I looked it up in the 'ol LSS. This specific lock was not in the book, but a similar one was. According to the author, this lock can be defeated with a lock scope, which I don't own. I rotated the dials and noticed you can see these cuts in the wheels quite easily, without any aid.

The cuts are barely visible in this photo, but looking at this lock in your hand, it is a lot clearer. By the way, these cuts are only visible when the lock is upside down, and you want the largest of the cuts, there are smaller ones that are visible as well. Now, I lined up these three digits in the are where you usually enter the combination.

By adding seven to this result, you will arrive at the proper combination:

Have fun
