Police are investigating the theft of the prop, which was being looked after by Elstree Props, a tenant based at Elstree Studios.
Managing director Stephen Wickenden told The Telegraph: "We have no idea who stole it or when it was stolen but things do not usually go missing."
The gun is thought to be worth £80,000 and was used as a prop by Christopher Lee, who played Bond's (Roger Moore) enemy in the film.
A spokesman for Hertfordshire Police confirmed that officers are investigating the theft.
Meanwhile, a spokesman for Moore joked: "You'd better ask Christopher Lee about this. Search his house."
