Thanks for the encouragement, sincerely appreciated!
A note about compromises, while I park this machine for the moment; judgement calls made about both accuracy and detailing.
As you can see, I gave up on double rigging. While I've seen it done in 1:72, sorry, but I haven't figured out a convincing and practical way to do it, by me at any rate. More importantly for these kits, when I noticed that there is indeed rigging on the tail assembly (as opposed to control wires), I was a little too far along to feel like fitting it in. Unfortunately, tail rigging doesn't feature anywhere in the Roden illustrations. Also, I have omitted some wires from around the engine assemblies. Laziness, I guess.
As far as markings and colour schemes are concerned, I've made some deviating choices. As regards the H.16, it seems, from a couple of pictures I've seen, that this particular machine didn't actually have yellow wings, but aluminium dope. Rather lamely, I'm imagining that it might have had some yellow paint applied later on, because it's hard to resist the look. I'll argue that many of the H.16s in that period did have fully or partially yellow painted wings, so it's 'authentic' even if not accurate.
The Chilean machine poses a different problem, in that the red and blue of the decals are badly out of register. For the large ones on the wings, I trimmed a rectangle and then painted white rectangles on the wings to place them on. But this was more awkward for the smaller ones on the fuselage, and I cut a corner there, leaving out the white outline. By the way, 'Zanartu' was the name of a midshipman who died performing a rescue, and the plane, donated by the British after the war, was apparently the first flying boat seen in South America.
