Ilford's statement was that they don't participate in rebranding their products any more, after the 2005 restructuring - this is something they reaffirmed when Kentmere 100/400 came out. But there's no reason they cant contract out their production line for other manufacturers, or even formulate new emulsions for them. They've done this in the past. It makes sense, they have a top of the line facility that's sitting idle between their own production runs. Just because its made on Ilford's machinery doesn't mean they're an emulsion that's already on the market.
That said, I have no idea what it is or where it comes from, so who knows.
