During World War 2 my husband’s father worked at Cruver Manufacturing Co., Chicago, as comptroller, later becoming sales manager, plant superintendent and general manager. His mother gave my husband the models that had been wrapped in newspapers and stored in cartons in the basement. Since the models were expected to become obsolete rather quickly, they were deliberately made with lower quality plastic than other molded products from the period, such as table radio cases. Some of the models showed signs of chemical breakdown in the black plastic they were made from. Please read the Condition Description as this plane definitely has chemical breakdown and fuselage distortion. No vinegar odor. Wing span is 7." Length is 5-1/4."
