Continuity mistake: After uncovering the motorcycle, there's only the tan chicken around. A moment later, Ralph has a brown chicken in his arm that wasn't there before.
Continuity mistake: As "Ralph" gets the chicken off the tarp covered motorcycle, he goes to pick up the egg with his left hand. After the close up, he does it with his right.
Visible crew/equipment: As Hawkeye, BJ, and "Ralph" come over to help the farmer, the shadow of the boom mic is on the ground at the bottom right side of the shot.
Continuity mistake: When "Ralph" has Hawkeye and BJ at gunpoint, saving their lives, the scenery behind them changes several times. Sometimes there's the road and a few trees. Then there's no road and a lot more trees and shrubbery.
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.
