Tim has quite a few unusual locks in his collection, and this combination lock has an uncommon design. There are ten black push buttons on the front, which when they are pushed in, then stick out at the back of the lock. You have to push in the correct four buttons, and then the lock will open. When you close the lock, you can then push all the buttons in, or if you push from the back, you can leave all the buttons in the ‘out’ position. An unusual design of lock.
