You could open this lock with two picking wires,one to lift the levers and one to throw the bolt.
You can see a picture of these wires at my web sight.
Click on the link below and then click on the lever picks section.

These locks are quite simple to open if you know what you are doing,but if you have never opened one before and have no idea how they work then you have not got much chance of opening it.
In case you fancy trying here is how it is done?
First up you will need two wires,the ends on both wires should be bent at right angles.
You then insert the first wire into the lock,right to the back where you will then need to turn it slightly to catch the notch in the bolt.Once you have done this you then insert your second wire and push this to the back of the lock.
Now whilst applying tension on the bolt with your first wire you must then try and lift each lever in turn until they all align,when this happens the bolt will give and the lock will open.
This sounds pretty difficult but it is quite simple when you know how.
There is also another pick that will open this lock which is the two in one pick,this can also be seen at the link above.
