No, only 2 ex Dundee streetlites are in Dundee green.I am sure there was a pic on flickr where one of the fleet was already in green before the Streetlites had been sent? If its not West Midlands would it be any of the other NX groups ie Coventry? Its just a pity had I remembered where I seen the pic on flickr I could post it
There is a bus at Wolverhampton Depot in Green as well. But thats one of the special heritage liveries and only 4535 carries that and not the same colour scheme used in Dundee.
