I think you need to determine what time period you are doing the skin for. If its late 44 then you need just the red and blue chevrons on the wings. If its January 45 and later then you need to add the yellow wing tips, yellow tail and bands around the rear fusilage shown in the pic on the 486th BG site AND add a band around the nose as shown in the other pic I pointed out above.
But it all depends on what time frame you are shooting for.
