I have a roll of Ilfochrome that I need to process, it was rebadged E6 film, Ilford have had links with Fuji & Konica. They made some Fuji B&W folms at one point, they've also made B&W paper for Japanese companies. Ilford aimed to return to the colour market in the late 1970's or very early 80's and so began marketing rebadged negative and positive colour films, they even had a designated piece of land (still empty) at Mobberly for a possible colour coating facility.

When I was in Istanbul about 3 years ago there was Ilford colour film on the shelves of the Turkish importer, I should have bought a few rolls.
