Color the Luftwaffe Red - S4-E8
Other mistake: The telephone booth located by the Luftwaffe HQ appears to be one of the London police boxes.
Guess Who Came to Dinner? - S4-E9
Factual error: Schultz says, Von Grubner has "a castle right next to the Führer's in Berchtesgaden." Hitler's famous real estate in Obersalzberg wasn't a castle but a mountain chalet based on a former farm estate called the "Steinhaus".
Guess Who Came to Dinner? - S4-E9
Audio problem: When Hogan says "Why is it you can only trust short, dumpy spies?" the movement of his lips does not match the words.
Continuity mistake: In Klink's quarters, Hogan is complaining about Berger's activities. As he does, he goes to eat a sandwich with his left hand. After the angle change, he has both hands on it.
Continuity mistake: When a German Major is in Col Hogan's quarters he is wearing black leather gloves. He raises his hand to remove his hat (with gloves). Next scene he is lowering his hat with bare hands. (00:02:10)
Factual error: Hogan and his men are in Berlin to capture a traitor. They arrive at the Hotel Berlin in an ambulance and park near a K2 phone booth, something only found in England and its colonies, certainly never in the heart of Nazi Germany. (00:13:55)
Factual error: The ambulance Major Teppel transports the prisoners in is a Dodge WC54, which is an American military ambulance, not a German one.
Other mistake: As LeBeau is being interrogated, on the barometer behind Schultz you can make out the word "fair." What is a barometer labeled in English doing in a German counter-intelligence headquarters?
Continuity mistake: As Major Tepple (Morrison) lays the deck of cards in Hogan's room on the table, the bottom card is not neatly in the deck. When the camera cuts to another angle, the deck is neatly stacked.
Continuity mistake: As the ambulance leaves the hotel, there is snow on top of the fenders and spare tire. Back at the truck, there is snow on the fenders, but not the spare. This would be impossible as at the speed driven, the snow would have blown off any horizontal surface.
Continuity mistake: As Hogan, Carter, and Newkirk go to get out of the Army truck, the ambulance doors are wide open. As Hogan walks by, the doors are straight out toward the truck.
Character mistake: After Le Beau is questioned, Schultz is told to take him back to his cell. Schultz calls "About face! Forward march!" The "about face" is wrong. The door that Le Beau goes out is on his right, therefore the command should have been "right face."
Continuity mistake: The trick ring Morrison has is on his right hand at the hotel, missing in front of the hotel, and reappears in front of German HQ.
Continuity mistake: In the lobby, Morrison has his gloves on, and never removes them. When he reacts to the gun shot, the gloves are gone.
Continuity mistake: Metsker never removes his right glove, as it is visible in all close ups. In the last wide shot, his glove is suddenly in his left hand.
Will the Blue Baron Strike Again? - S4-E12
Factual error: The "Blue Baron" tells the dancer that the Kaiser gave him a certain medal. In fact, the medal he points to (and the girl fondles) is a WW2 repeat badge to the Iron Cross first class, instituted in 1939 to denote presentations of the Iron Cross first class to personnel who had already received it in WW1. He may have received the original Iron Cross from the Kaiser, but by the time he had a chance to receive that repeat badge, the Kaiser was long through handing out medals. (00:15:10)
Will the Blue Baron Strike Again? - S4-E12
Continuity mistake: The cigar Hogan takes from Klink goes from green to light brown when starts to name the top invitees to the party.
Will the Blue Baron Strike Again? - S4-E12
Continuity mistake: At the airfield, Carter and Newkirk go to move, Carter steps left, and falls into the water. Newkirk takes a step, and leaps into the water, losing his hat, and trying to make it look like Carter pulled him, but you can see him looking to the way he falls. When the camera angle changes, Carter is splashing about, and Newkirk walks up to him from the left without having gotten out from where he fell. And his hat is on, despite losing it from jumping in.
Will the Blue Baron Strike Again? - S4-E12
Continuity mistake: When Hogan is listening to Kinch, his overcoat is open. When camera cuts from him to Newkirk and Kinch and then back, Hogan's overcoat is shut.
Will the Blue Baron Strike Again? - S4-E12
Revealing mistake: When Hogan, Newkirk, and Carter are at the Blue Baron's secret airfield, Hogan opens the barrel and stuffs in a rag and lights it so it will be a flare for the Allied bombers. The flight line and the planes on it are an obvious cutout. The fire couldn't have spread to the surrounding ground like it was shown. Also, when the bombs were going off on the airfield, you can see that the explosions are very small charges behind the cut outs.
Answer: It's a comedy, not a documentary.

Perhaps it was counterfeit. There are numerous episodes where they deal in counterfeit monies.
