Notes

Production began in December 1926. See Douglas II, p.48, an ad from Sept. 1926, where the model 30 is announced. Also available as Table model 40. Two dials (primary tuning control knobs) .
Radio Attic shows a table model 30. There is no evidence for such a later version. Probably wrong allocation. Does not belong to the console here (as pictured in ref. Douglas book)!
