That's a very nice collection of Canberras and B-57, Tony.
Where is the B-57G from? At first I thought it would be a mod of Bruno's 1:300model but the canopy is completely different. Did Paragon make a B-57G?
One version that's missing is the Canberra B(I).8 with an off-center teardrop canopy. That one could be used to make a New Zealand or South African B(I).12, an Indian B(I)58 or, with the appropriate stretches, a PR.9.
