Can’t find any reference to 612 Sqn operating Meteors on active “duty” so this could be the markings of another “hack/comms” aircraft yet to be painted. Problem is 208 came from 611 which had triangular patterns....
As has been said above 612 has green background with 2 rows 10 blue rectangles alternatively spaced with thin and thick green stripes...

Whose are the Sabres behind?
