Superb! One of my favorites, second only to the Hawk. I have two of Alistair's Tucanos on the way across the Pond.
As to the question of doing a Tucano in the Diamond Jubilee scheme, if anyone has information on the availability of decals for this, please let us know. Even 1/72 would be nice, in my case, for the Pioneer kit, as i haven't been able to locate the Airfix kit, with or without the DJ decals in six months of searching. I believe the lack of these may have to do with strict copyright issues with the Crown symbols and such.
Enjoy the modelling. Ric
