The Westinghouse AR, DA, RA, RC, & RT were among the first products marketed by RCA and were made by Westinghouse ... that is all except the German made version (shown below). The "RC" consist of the "RA" & "DA" housed together in the same cabinet. When the individual units were hooked up and working together the combination is known as the "RADA".

The Westinghouse AR, DA, RA, RC, & RT were among the first products marketed by RCA and were made by Westinghouse...... that is all except this version of the "RC". The "RC" consist of the "RA" & "DA" housed together in the same cabinet. When the individual units were hooked up and working together the combination is known as the "RADA".
I have owned this unusual version of the "RC" for more than 40 years. Although it's size, layout and cabinet are identical to the Westinghouse built units, there are distinct differences in the knobs, dials & internal components. On the rear the spacing of the terminals are slightly different and the thread of the binding posts are much coarser than that of the "Westinghouse" built units. The differences do not stop there. Internally the audio transformers, capacitors and almost all components are completely different. You can note those differences as I have provided several images of the insides.
For the last 30 years, I have always thought that this particular version was not made by Westinghouse and until 1998, none of the many experts I consulted knew of it's origin either. After posting the images on my web site in 1998 several fellows provided me with some info that it was made in Germany by Telefunkon, one implied that it was imported through Canada and "bootlegged" to the US (the reason there are no ID plates).
Recently Mr. Konrad J. Birkner (a German citizen and radio collector), was kind enough to provide me with the following information, below are his words:
"Telefunkon and RCA had made a patent exchange agreement in 1920. The set in question is a legal product, not bootlegged !
The manufacturer was "TELEFUNKON" model "D 304".
The threads are metric, and components are of the
manufacturers make make. The sleeves of the tube sockets are perhaps slightly narrower compared with the Westinghouse models. Telefunkon even offered a tube "RE 58" which was similar to the UV 201. Sometimes an ordinary American UV/UX 201/201A would jam in a "German" socket. Heaven knows why....."
