I try and keep the fleet lists as up-to-date as possible. I class the livery 4663 carries as 'Original Arriva', and the one 4662 carries as 'Arriva'.
Must admit, although i didnt look at this before making the comment, my own personal fleet list shows 4663 as been in the Arriva livery (arriva following your system).
