Here, it looks normal, it could be used like this, no problem

This is the back end of it, the screw holds the KIK in the housing.

KIK removed, showing pins with no key inserted. There are 4 spools and 3 serrated key pins.

Correct key inserted, and plug rotated.

Wrong key inserted, notice the one serrated key pin.

Personally, I love cutaways, this one can be tricky to pick with the security pins, and I like how I can easily put it in the rim cylinder, makes holding it or mounting it on the lockboard a lot easier.
I had a lot of fun with this one, but I think I'll sell it soon...
