It is correct! There are pictures posted (or links, at least) on another forum. The four marker lights (not headlamps!) were fitted to early batches but at least a few WR examples did get into blue and grey. Most, if not all, had the two centre lights painted yellow.

Check your facts before pointing fingers, please.

Admittedly it's a Scottish Region unit but it is dated 1984. No red buffer beams but the overall livery and appearance is correct. Agreed, Hornby do seem to choose rather limited prototype/liveries to model. There wre a few Western Region ones like this but I don't know vehicle/unit numbers.
