Manfroto two thread grip head (1 Viewer)

I know I've seen an image of this somewhere, but now my searching of the internet has revealed nothing!

I've seen a set of manfroto legs with a special grip head on them. There are threads at the ball and at the top of the grip, essentially allowing you to mount a camera and a spotting scope at the same time.

I'm pretty sure the one I saw was binoculars and a spotting scope. Has anyone else seen this? Maybe have a model number? I asked at my local camera store that does deal in manfroto, but they gave me a blank stare.

Is this what you were thinking of?
