Which Matte Box in this Photo?

Is it the Chroziel?

No, it looks like a CAVision to me. I've never seen a bellowed Chrosziel.

Thanks, Ken.

I can't identify it, but I must say that some of the Chrosziels do have an internal bellows, Ken (I have a Super 16 mattebox of theirs that has this feature). It has the plastic hard shell but the inside is fabric bellows that can be adjusted fore and aft to maximize the flare protection. I'm not sure about their smaller boxes though.

Ah, thanks for that Charles. I've only seen those with the flat, flocked black interior surface (like my 4x4).

Hey, that's really hard to say 3 times:
flat flocked black,
flat flocked black,
flat flocked black

this is the one baby:
