The early scene in which M [Bernard Lee] orders the reluctant Bond to part with his Berretta, defines the relationship between the agent and his superior, M tells Bond...If you carry a double-O number, it means you're licensed to kill, not get killed...You'll carry the Walther, the gun is then presented to him by Major Boothroyd [Peter Burton] who tells Bond about the gun's credentials ...the Walther PPK 7.65mm with a delivery like a brick through a plate glass window. The American CIA swear by them. This part of the script reveals an error made during production as the gun supplied was in fact the Walther PP and not the PPK.
The Walther handgun has become synonymous with the character of James Bond, and is his trademark; it is without doubt one of the most recognisable and iconic film props in cinematic history. BAPTY have confirmed that this Walther PP handgun was the only one supplied for Dr. No.
