That would not surprise me at all. I remember someone (Maybe Ron Ramirez, God rest his soul) posting a note that Philco was not above splicing the magnet wire used to wind RF / IF transformers, especially single layer jobs.

Philco was a very early user of 6V tubes as they were developed for car radios and Philco was a major supplier of car radios. I believe that Philco converted to 6V tubes in transformer powered home radios in 1933.I believe that RCA did not switch over to 6V tubes on transformer powered sets until the 1935 model year, although they were using 6V tubes in series in transformerless sets, and in car radios in 1933.
