No way were these intricate and difficult models aimed primarily at a market lacking the skills to build them well...though many of us as youngsters, including me, made horrible bodged messes of the best of them."
The55,56 57 Chevy, the Swindler Willys, the 57 Nomad and showrods all had doors, hoods, trunks or bubble tops that opened. Tiny hinges on the 29 pick up all things that steered me away from Revell as a young modeler. Metal axles and easy install clear parts was my route back then.
