A Walther LP53 was however used in a promotional photograph for the film From Russia With Love and apparently some others.
The story of why this occurred:
Lot Notes from Christies: "The original vendor, who was commissioned to shoot the images required for the publicity campaign for the second Bond film From Russia With Love, explains in his accompanying letter that "it was decided that for the main image in the poster and advertising campaign what was required was a strong portrait of Sean Connery as Bond 007, with his Walther pistol" He explains further that when Connery arrived at his studio for the shoot, it was discovered by publicist Tom Carlile that no one had brought the gun needed for the shoot, the synonymous small Walther automatic [Walther PPK]. By chance the photographer practised air pistol target shooting as a hobby and had the gun he used for this purpose, also a Walther, at the studio "it was decided that - without telling Sean or the other representatives of United Artists - we would use my pistol for the pictures and presumed that should anyone have doubts on their seeing the name Walther on the gun, they would be reassured.
At a Christies auction of 25/11/2010, the Walther LP53 air pistol held by Sean Connery as James Bond in the photo-shoot used for the main image in the poster and advertising campaign for the 1963 United Artists/Eon film From Russia With Love has sold for a staggering £277,250 (around $430,000), more than 10 times the estimate.
