Help identifying weird ASSA lock

So, I got my grubby little paws (or whatever you'd expect someone named after a starfish to have) on this ASSA lock with an odd-looking profile that I don't recognize:

It's a 6 pinner. No SCD (Security Cylinder Drillproof or whatever) mark and no visible drill protection pins. When seeing it mounted in the door I kinda assumed it was some mongrel Twin because the profile is clearly meant to accomodate something on the lower left side. There is also some sort of pins in there, but only two of them and they move in the wrong direction (left, not up) and probably sit too low to ride on a sidebar. Passive profile control pins? Except they're springloaded...
I suspect this is meant as a less-secure lock for inner doors in a larger Twin system? Except the keyway isn't paracentric, which I would expect in a higher-security system.
Right now my mind, or rather my fingers, are working on something else entirely so I haven't checked out the pinning. Should be easy however - it has one of those screws in the back to let you repin it without taking out the plug.
So, any clues? I though I knew ASSA profiles by now :-).

Hummm .... doesn't really help with the pic being so out of focus, I'm sorry to say. Any chance of a better pic?

Yeah, my camera is ... not great at short distances. I was hoping being able to see the general outline of the profile would be enough.
Another attempt:

Apparently this is an ASSA Twin Combi 1800. It's, just as I guessed, intended to be used for low-security doors in a system with the Twin Combi 5800.
