| Histoire: |
DeForest Radios suffered from the lack of regeneration. An Armstrong license was urgently needed.
This happened by acquisition of a defunct company, Radio Craft, which had bought such an Armstrong license from Westinghouse for not less than 10,000 $!
Radio Craft's ads disappeared after June 1921.
Early in 1922 DeForest bought the firm. But Westinghouse objected against the license transfer. Consequently the Radio Craft Company was officially maintained in a partitioned half of the DeForest factory.
The regenerative Radio Craft receivers were advertised now side by side with the non regenerative DeForest models. We put all Radio Craft models (which are extremely scarce) together with the Deforest listings. Often there are problems to distinguish, since for a short time DeForest even offered regenerative models under their name (in contempt of court judgement!). Such panels were discovered on the DeForest side of the factory.
