Dear Mildred - S4-E7
Continuity mistake: The injured horse that Radar, BJ, and Hawkeye go after, and who's later gifted to Colonel Potter, is played by different horses.
Continuity mistake: When Radar and Burns leave the tent for morning parade, Radar's clipboard acquires a pencil. (00:02:50)
Continuity mistake: Along with Radar holding an anachronistic comic book (the Avengers), the exact issue changes between wide and close shots. One has the older Avengers logo used in the '60s and very early '70s, while the second issue Radar is holding has the newer Avengers logo that just gained currency as the episode was being filmed. (00:00:45)
Continuity mistake: When Hawkeye is examining the orphan who is wiggling his tongue, there are two camera angles: one of Hawkeye from the front and one of the orphan over Hawkeye's shoulder. In the first shot, the tongue depresser that Hawkeye is holding is horizontal, in the other it is vertical. This flips back and forth a couple of times. (00:06:30)
Continuity mistake: When Margaret pins on Frank's purple heart, his scrubs are very damp with sweat. When he enters the swamp, they're practically dry. (00:03:50)
Continuity mistake: After Hawkeye and Burns drive through the puddle, the mud on the colonel's face is different in the long and closeup shots. (00:02:00)
Continuity mistake: When Jack delivers the patient to the MASH and when he is taking photos of the operation, there is no wound on his right hand. It only appears when Col.Potter says that he treated it "months ago". (00:04:30)
Continuity mistake: During the shelling on the road, BJ gets very muddy. When they get to the bar, he is much cleaner - e.g. all the mud has disappeared from his right arm. (00:44:30)
Continuity mistake: When Hawkeye and Radar leave the 4077 in the jeep, the last three numbers on the hood are "717" but when they get to Kimpo it's a different serial number ending in "388."
Continuity mistake: When Radar and Hawkeye leave the 4077, the jeep they're in has its windshield in the fold-down position over the hood, but in the two shots from behind Hawkeye and Radar when they see the checkpoint up ahead and Hawkeye speeds up, the windshield has vanished and there's a star on the hood.
Continuity mistake: After speeding past the checkpoint Hawkeye's stopped by the MPs, and when the lieutenant takes hold of one of Hawkeye's dog tags he's holding the one on the extender chain, but next shot he's holding the other dog tag, with the extender chain and second dog tag hanging down.
Continuity mistake: The "KILROY" Hawkeye writes on the window as BJ looks out was in the center with his fingertip. Later, as Hawkeye looks out, the "KILROY" is now closer to the frame, and the lettering is different, a small capital A in front of it, and lines above and below it.
Continuity mistake: Early in the episode it is stated that Margaret's tent door is padlocked while she is in Tokyo. But when she gets back, she just walks straight in. (00:22:20)
Continuity mistake: In the assembly called by Major Burns at the beginning of the show, Klinger is in the front rank far left (except when the continuity error has him centre rear), but after the appearance of Hawkeye in the rickshaw Klinger isn't on parade at all.
Continuity mistake: Before The Sniper starts firing, Hawkeye is carrying the two bottles of scotch firmly gripped by the necks. A second later, he's barely holding them by the caps, in preparation to drop them.
Dear Mildred - S4-E7
Continuity mistake: When Colonel Potter's in his office finishing up his letter to Mildred, right before Margaret, Frank, and the others walk in, the things on his desk change their positions between shots - such as the paper tray moving from Potter's left to the right side of his desk.
Continuity mistake: After Jack wins a drink from Hawkeye and BJ, Hawkeye grabs the orange to inspect it for tears to prove his magnet theory. After the angle change, he grabs it again.
Continuity mistake: As the interviewer talks to Hawkeye, his hand alternates from just below the microphone head to just above the bottom end between angles.
Continuity mistake: When Carly is talking about Hawkeye being a "mortician's delight", she is gesturing with her right hand, and it's about waist height at the end of the motion. When the camera goes to a wide shot, her hand is up by her chin, about eight inches from her face.
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.
