Here at the Crystal Palace Exhibition, Hobbs, designer of the Protector lock, became the first man to pick the said unpickable Chubb detector lock.
The Protector lock also called the moveable lock was an early 1850s lock design by renowned American locksmith Alfred Charles Hobbs, the first man to be able to pick the six-levered Chubb detector lock at the Crystal Palace Exhibition in the year 1851, which was created with the intent of being a lock that could not be picked.
Before Hobbs and his revolutionary lock designs, locks were opened by making a series of false keys, in a process that could take extremely long periods of time; if the series was not properly completed in the lock, and the combination not exactly correct, the lock could not be defeated. This design was accepted as quite unbreakable until Hobbs became the first to be able to pick them, by using very fine and careful manual dexterity; applying a certain level of pressure on the bolt while manipulating each lever, one at time, using a tiny pick inserted through the keyhole. 1
In an attempt to create a better locking system, Hobbs proceeded to patent the Protector lock, which, complex in design as it was, involved a transfer in pressure between the lock s internal bolt and tumbler mechanisms to a fixed pin. 2 Hobbs claimed that his design was impossible to defeat and superior to the locks that were then in use, but, in 1854, one of Chubb s locksmiths was able to crack it, aided by the use of special tools. 3
The Protector Lock was distinct from Hobbs s other major lock design of the time, which he called the American lock, and which slightly preceded the protector lock, in various ways; while the American lock was complicated to use, and expensive to purchase, with the added disadvantage of requiring a very big key, it did not differ greatly from the Protector lock so far as the security it offered, and the Protector lock was described as being much simpler to use. The one advantage that the American lock did have over the protector lock was its actual potential for greater security, if certain internal parts of the lock and key were rearranged in a particular way. 2

How to pick Defcon CL combination lock with off-white cover.
Exterior looks like:

There are some videos on how to pick it with a shim in the end, but it does not work on ones with off-white plastic.
This is how the lock works, imperfect but gives a good idea:
This is how you may bypass it:
The whole thing comes down to feeling out unusual friction as you turn the wheel due to imperfect manufacturing. they are all more or less imperfect
1. Push down on the button. Keep pushing it down the whole time you are cracking.
2. Start spinning a wheel, I like to start from the far end.
3. This is the biggest part. Listen, feel for a click, pop, or any odd sound or feeling. Basically you are feeling for one of the fingers to get a little bit stuck or behave a little differently because they are clipping the edge of the hole they may have been over.
When you notice such a click or a pop, turn the wheel back to the number, that turning from brought a click and turn it to and from that number, both ways, feeling for clicks. If after doing this you feel like that number may represent a hole because of the clicks surrounding it, then you have a possible number. If it is a a number another number will be 3 numbers away in either or both rotations so subtract or add three. You may or may not feel these as well. Repeat this process on each wheel, leaving the wheels at the numbers you have found.
4. If you have truly found a number on each of three succeswheel where at least one of the fingers is positioned over a hole, then once you get to the fourth number, turn it around until it is stuck. The other wheels will now be stuck too. They will also stick on the other holes. They are spaced -o-3-o-3-o-6-, or 90, 90, 180. Just look at the image I have provided. You re pretty much home free at this point.
5. Now we are looking to to have the number represent the middle hole. So simply turn each wheel until it is stuck on a number which is surrounded by a number on each side which is 3 turns away and it becomes stuck on. Once you have done this for each wheel, the lock will open.
Let me know if anyone has some good tricks for finding notches in combination locks.
I may upload a video later if there is a demand.
