Is it possible to reverse engineer WNW moulds from a set of sprues?
If so, I'd expect to see Chinese kits of subjects that look remarkably similar to existing WNW kits, but with subtle changes - perhaps rubber tyres, brass gun barrels, altered surface detail - fabric folds moved - PE instrument panels, moveable control surfaces &, of course, different decals.
After all, the Chinese have made exact copies of Mini's, Land Rovers, Audi A8, Porsche Cayman, BMW X5, VW Up, Mercedes C class, Range Rovers and even Teslas in the past, with different badges nailed on the front alongside tweaked wheels, grills & panel lines.
If they can do that, copying a kit should be easy-peasy. Chinese industry - aided by the government - have not really grasped the concept of copyright & intellectual property. I expect there's more than a few injection moulding operations that are looking for work at the moment.....
