Piece of gear... Head harness ball gag

I saw a video I believe was of a model named Emma in bondage on the deck.  One piece of gear that was used was a head harness ball gag.  This was pretty much the standard head harness with the inverted "Y" partially over the eyes, but it was different.

There wasn't a standard chip strap.  Instead there was a long strap.  Instead of going just under the chin this strap wrapped the neck one and a half times, holding the gag down in place.  I found that to be quite erotic.  

Any idea where a piece of gear like that came from?  Or was it custom?  I've never seen it for sale or in any other productions.

Oh, and the model was pretty hot too, but I don't know who she was
