The oil canning looks like Airfix got it right there. Too bad they had to muck it up with bad fuselage mating areas. But this is something I am sure you will effectively deal with Don.
Little update..
I have a couple bottles of Tester's enamel dark sea blue left in inventory so I stated by mixing near 1:1 with thinner in fresh Tamiya mixing jars.
which brought the viscosity to a workable level. I shot half of each wing and part of the fuselage.
Working seams on fuselage and while that's drying I started the engine build.
There is a lot of clean up needs to be done!
Test fitting, TIGHT fit.
The push rods don't line up. Everything is keyed so that's a minor problem. Very tight fit and nearly broke off a push rod.
Tamiya black panel liner helps the cylinders stand out.
Still a lot to do here.
