Notes The Co-op models 6AWC2, 6AWC3, 6A47WCR, 6A47WT and 6A47WTR from National Cooperatives Inc. are using the same chassis. They are AC operated 2 band superheterodyne receivers with loop antenna. The data for the cabinet is taken from the 6A47WT and duplicated to the others. Therefore it is uncertain if all models are made in wood and table models. The short waves are 9 - 15.6 mc.
