The prop firearm, a replica of the gun used by Francisco Scaramanga, the arch-assassin in the ninth Bond movie, "The Man with the Golden Gun", is autographed by Roger Moore and comes complete with a replica bullet engraved 007.
It is just one of nearly 500 lots of entertainment memorabilia set to go under the hammer at London auction house Bonhams, and is estimated to fetch between 3,000 to 4,000 pounds.
The replica gun up for sale is the only one known to be signed by Moore. Made by S D Studios, Ltd, it carries the limited edition number 377/7500.
Like Scaramanga's gun in the film it is assembled from a dummy Colibri lighter, with dummy pen as the barrel, signed dummy cigarette case for the butt with a dummy cufflink trigger.
Just over 10 inches long, it comes on a wood mount with descriptive plaques, complete with a replica bullet engraved 007, just like the one sent to Bond in the film.
Released in 1974, The Man With The Golden Gun featured Christopher Lee as Scaramanga, the world's most feared assassin, who gets embroiled in a plot to steal solar power technology.
Believing Scaramanga has threatened to kill him Bond, played by Moore for the second time, travels to the Far East to confront the assassin, who kills with a golden handgun which can be dismantled into harmless looking gentleman's accessories.
Bond discovers Scaramanga's plot to steal the British-designed 'Solex agitator' but in trying to foil the theft his assistant Mary Goodnight, played by Britt Ekland, gets locked in the villain's boot and whisked away to a private island in Red Chinese waters.
However, thanks to a tracking device Goodnight had been carrying, 007 is able to fly a sea plane under Chinese radar to land at Scaramanga's island.
There he fights a pistol duel with the assassin, who is wielding his golden weapon. Scaramanga tries to trick Bond, but the spy is able to outwit him and kills him before escaping with Goodnight on a Chinese junk.
