MAN demonstrator?

[Ossie]

I saw, in the twilight last Saturday, on the A5 somewhere around Dordon, what I recorded at the time as WX12FKO - which I now think after googling was WX12EKO, a MAN CitySmart demonstrator - it was black and white with a sort of wavy brown livery ...... 

Now I think it was displaying route 75, which could have been Wood End - Atherstone, which would fit the location, and would make it on loan to De Courcey?

Can anyone confirm it's De Courcey, please?
