If my memory is right
the graphics on the cleaner which has the "brushed edge cleaning" comments on the motor hood are all consistent with a redesigned style of Turbomaster from about 1991, where the graphics on the headlamp also changed (as you will see it says Turbo master and not carpet selection, and the icons were different too). The cleaners had the brush roller with the green bristles on the outer edge, and the three-piece tool kit was the later style with grooves around the neck of the accessory.
The Royal warrant, or more so the absence of such, is a different matter. Cleaners which were not made for the UK home market often did not have the Royal warrant stamped onto them. The options for this cleaner are likely to be that it was not made for the home market, or has had a replacement bag door (it is not unknown for them to break), or it was the last of a production run when stocks of an existing bag door was used, though of course this is not consistent with the date on the rating plate.
