However, I am still interested.
But we may not discuss here everything because the topic can be closed.
My lock is not new and has well worked before.
Unfortunately, the right Combination does not work now.
Maybe a disk is rubbed off in internal one of the lock
and so I am not able to put it on "Nul-position"
I have already tried out a lot of other combinations.
( after I have read an article on the Internet ).
And once the lock has opened.
But I cannot make this over again. And I don't know, why.
Now it is closed again.
