Visible crew/equipment: As the M.P. jeep escorting the General's jeep gets close to the camera, a reflection of a lighting rig or reflector is seen in the right windscreen.
Answer: The C-42 was a military variant of the Douglas DC-2. Very few C-42's were built, so it's questionable that Potter would specifically have seen that particular model, but, given his military background, it's not entirely unreasonable that he might use the military designation even when the aircraft in question is actually a civilian DC-2.
