Really old question
Watching some reruns on history hd and I got to season 3 ep 4. A guy wants to sell an aircraft dome, with an attached manufacturer tag. All is well and good until I freeze frame on the date of manufacture: 9-31-53.... Lower on the tag references a date one year late 9-31-54.
There is no mention of this mistake even by the expert. Am I crazy of does September only have 30 days?
