• Notes

• The battery operated Sparton model 6-26 has a one dial (primary tuning control knob) operation. The ad September 1927 of "Radio Retailing" page 15 includes the models 6-15, AC 6-15, 6-26 and AC-7. The model shows a slightly different face in the ad between July and September 1927, but in July it might have been only a make up for photography.
