Other mistake: Moriarty writes the fourth name and address of Tobel's code; he spells "Frederick Hoffner Sloane." However, as he reads the paper on which he has written the words, he also reads the word "Square," even though he has not written it. (00:54:35 - 00:55:00)

Revealing mistake: Inventor Dr.Tobel is shown with his bomb sight. Later in the film we see the same equipment, only this time it is Sherlock Holmes' ultraviolet light apparatus. (00:22:05 - 00:45:30)
Trivia: Lionel Atwill, who plays Professor James Moriarty, had already played Dr. James Mortimer in the 1939 movie "The Hound of the Baskervilles," with Basil Rathbone and Nigel Bruce.
More questions & answers from Sherlock Holmes and the Secret Weapon
Chosen answer: It's possible. Even during WWII, people were less savvy about protecting personal information, particularly as asking for a home address seems innocuous enough as opposed to giving out government or military info. Of course, this is a movie, so some liberties are taken to serve the plot.
