"Radio Retailing" November 1935 - new models - means that at least early October the sets were ready. The majority must have been sold for Christmas. The following upright table models were offered as new: 4015, 5619, 6616, F-M 7117, 9018, 4115, 6416 and "down-to-the-floor construction" consoles 5645, 6645, 7146, 9047 and 9048 plus the battery model 6445B. The first digit tells the number of tubes. Plus models 11049 and F-M 11050 with 11 tubes. Fairbanks-Morse called its new loudspeaker and AF technique "third dimension tone".
