The Last Adventure (original title Les Aventuriers) is a 1967 French-Italian movie directed by Robert Enrico and starring Alain Delon and Lino Ventura. The movie is based on a novel by José Giovanni.
The following weapons are seen in the movie The Last Adventure:
Two Luger P08 pistols are among the German weapons found by the young boy in the old fort. One of them is a long-barreled "Artillery" model. During the final shootout Manu Borelli (Alain Delon) uses both pistols.
The Mercenary (Hans Meyer) uses a pocket pistol with sound suppressor (which is possibly fake) when he interrogates The Pilot (Serge Reggiani). This pistol is most likely a Spanish copy of FN Model 1905 in 7.65mm calibre (like Victoria, Ruby or many other so-called "Eibar pistols").
During the shootout with the patrol boat The Mercenary (Hans Meyer) is armed with the Beretta Model 38/42 submachine gun with a short box magazine, supposedly for 20 or even 10 rounds.
In the final scene one of the henchmen of The Mercenary is armed with MAT 49/54 submachine gun, a version of MAT-49 with fixed wooden buttstock and a long barrel.
During the scene on the yacht all main characters shoot Winchester Model 1894 rifle. The Pilot (Serge Reggiani) use this rifle in the scene of the shootout with the patrol boat.
In the flashback scene The Mercenary (Hans Meyer) is armed with M1 Carbine. It is also seen in hands of one of the native rebels. In the final scene one of the henchmen (Guy Delorme) of The Mercenary is armed with M1 Carbine. After he was shot, Roland Darbont (Lino Ventura) took his rifle and used it.
Several Mauser Gewehr 1898 rifles are among the German weapons found by the young boy in the old fort. These rifles weren't used in action by the characters.
About a dozen Model 24 Stielhandgranate grenades are among the German weapons found by the young boy in the old fort. Several of them are used by Roland Darbont (Lino Ventura) during the final shootout.
The final scene of the movie was filmed in Fort Boyard, a sea fortress at the west coast of France. When the film was made, the fort was seriously dilapidated. It was subsequently restored in the late 1980s to provide the venue for a popular French TV reality show.
