A 1/700 Ark Royal from WW2 is nice, on realism maybe the hangar openings in front are not in correct positions, but compared with the real one is accurate as scale allows.
Maybe number of Swordfish available to put on it is little although folding wings is a nice feature.
However aircraft in 1/700 is always better to custom make them, never did it but an idea will be to scale drawings with sections, using plastic sheets make the structure with the sections and then use fine aluminium sheets on that structure (about the glue to use for metal-plastic not sure) and wet paper for fabric surfaces, for radial cowlings and wheels just plastic cylinders. Is a task for someone that really like to do that, or have experience.
