THX for the excellent preview of the likely 139 scheme. However, I submit that the roundel will appear on the tail boom rather than the main cabin door, and that hopefully IRISH AIR CORPS will appear on the main cabin door. Likewise, the serial number may appear on the tail boom beside the roundel and on the nose for easier observation on the ramp and in the field. This from experience trying to find the proper aircraft on a crowded ramp.
Finally, I strongly support the single color scheme and hope it is a shade of dull green similar to that now used on British Support Helicopters such as the Chinook and Sea King.
