This is a rare item and can only have been produced at the end of its production run. The paintwork is worn and the rear suspension has gone. I have repaired that and the model displays very well now, with good screens and interior.
The other components of Gift Set 41/48 may have had these cast spoke-effect wheels and so it may be reasonable to assume that Corgi decided to make the Rover and Hillman match, there already being Cortinas and Mini Coopers issued with them. I don't know, of course, but a maroon Rover recently came to light and that and this Hillman are the only examples I have seen in many years so, whatever the case, they're scarce indeed.
