Trivia: The pictures painted by Col. Potter throughout the show actually were painted by Harry Morgan, the actor playing Col. Potter, who is an amateur painter in real life.
Suggested correction: According to all sources, Harry Morgan didn't paint the pictures. The prop master hired local talent as needed.
Trivia: After Harry Morgan joined the cast as Col. Sherman T. Potter, the character is shown numerous times painting portraits of the main characters. However, he never painted them. The studio prop master farmed out the work to local talent who was happy for the work. None of those artists have been named.
Suggested correction: This entry is contradictory with another Trivia item which states that Harry Morgan, being an amateur painter in real life, did indeed produce at least some of the paintings.
Other mistake: Many times during the series, soldiers are around the OR carrying a loaded weapon (magazine attached for example), when there is a sign outside the entrance that says "all weapons must be cleared before entering the building" or similar.
Suggested correction: With the rampant rule breaking seen in the show, why would this be a mistake?
