They have a glass tube surrounding the cylinder designed to break and jam the pins in the event of a forceful attack such as brute force or indelicate picking. In addition to the "normal" pick tools, you'll need 30 lb. ball bearings and some anti-freeze. Preferably Quaker State.
There are a lot of Fetzer clones out there. We need to see the entire lock to be sure of it's brand/origin. To the original poster, can you please post a couple of additional pictures, this time showing the entire lock, preferably front and back. It's important that no part of the lock is left off the picture, some of the clones are VERY close copies.
MortimerDuke, why Quaker State? I've never found any difference between brands, as long as you're using an antifreeze that's Ethylene Glycol based. Although admittedly you want to avoid a Propylene Glycol based formula.
