The radio at Axton's ranch is an extremely rare 1935 Zenith model 1000Z "Stratosphere". Only 350 were made and it was priced at $750 ($16,600 in 2023). It used 25 vacuum tubes and its cabinet is made of inlaid walnut, elm and laurel woods. It had a then cutting-edge automatic volume control. In 2023 these radios, completely restored, can fetch over $50,000. It is the "holy grail" for radio collectors and museums.
Child actress Juanita Quigley appears in new footage shot for and used in the movie's trailer (she did not have nor was intended to have a role in the actual movie).
The biplane seen near the end of the film is a 1929 Spartan C3-165. This same airplane was used in Five and Ten (1931).
