I would flag it as Private label made or at least packaged by Ilford.
.
You may be right but to be sure I wonder if Simon Galley will tell us if Ilford use its own backing paper and ringed dots notation on film it makes for a Private label. For instance it is said that Ilford makes Fuji chromogenic 400 film. Well if it does make that other maker's film does it use Fuji backing paper or its own and has it ever made an unknown, unspecified Private label. Still more questions than answers
