We can see the Iophil logo here:
http://www.danone.pt/somos/historia.aspx
in "Anos 70"
The two reds stripes, the lower larger than the higher, that we see in this Rover is just the same tipe just like in the transit vans on the Danone site.
On the Bonnet just beetwin the headlights, we can still see the remais of the Danone lettering, that means that this livery was after 1989.
