A fellow on ARF sent me the following link:

In the 1928 article there is information about using the 171 tube as a detector.
Additionally, he noted the presence of a rheostat with the UX199 and stated that it was common to use the 199 as an RF tube in sets like this one due to their low inter-electrode capacitance. The rheostat would drop the V for the 199's filaments.
Very interesting...!!
