I'm not sure that you can definitively say it is not being manufactured by Ilford.
I think that Simon has said that they will not supply their own Ilford product to be labelled as someone else's house brand. I do believe, however, that Ilford do manufacture other products to the specifications of other parties.
As I understand it, Ilford's facilities and people are available for hire.
And they are in the EU.
One has to distinguish betwenn Ilford (brand) and Harman (company).
I understand that Harman told us you will not find a film / paper sold under the Ilford brand and another one. The Kentmere label is another story...
