One historical reference to an Arborphone 35 that I have found is an advertisement from the May 1928 Radio Broadcast magazine.
The ad boasts of the Loftin-White circuit and at first I assumed it would be the same circuit used in the Arborphone 37-AC and 55. However those two radios use an 8 tube circuit while this ad claims a 7 tube circuit for the 35 model. The ad also states that the 35 model is available in a variety of cabinet and console styles. Other than the early Arborphone, the front panel dimensions are the same throughout the Arborphone product line, at least on the subset of Arborphone radios that I have collected.
