Indiana Jones and the Last CrusadeIndiana Jones and the Last Crusade - Internet Movie Firearms Database - Guns in Movies, TV and Video GamesIndiana Jones and the Last Crusade
It appears that the revolver Indiana Jones (Harrison Ford) changes to a Webley "WG" Army Model when he is seen taking it out of his waistband to shoot at an oncoming German fighter plane, only to find it with no ammo. He is later seen firing it when chasing the German tank that holds his father and Marcus Brody.
Walter Donovan (Julian Glover) carries a Walther PPK as his sidearm. He first holds the pistol on Indiana and then on Henry Jones, Sr. (Sean Connery), in order to get Indy to retrieve the Holy Grail for the Germans. It has been said that the use of a PPK to shoot Connery's character was intentional as a nod to the James Bond films (in which he carried a PPK). Another weapon of this model is used by the female German Communications Officer that spots Indy and his father when they are tied up in the room that's set on fire.
The Walther P38 is a very common weapon in this film, used by a large majority of the German Soldiers and Officers. It is also seen used by Indy during the tank chase, using one to shoot three German Soldiers in a row. Later in the caves, Sallah (John Rhys-Davies) is seen armed with the Walther P38.
Kazim and his men in the Brotherhood of the Cruciform Sword use Mauser C96 pistols in Venice, most notably used to pistol whip Marcus Brody, knocking him out.
A 4 3/4 inch Colt Single Action Army revolver is carried by the grey haired grave robber during the circus train chase. He points it at young Indy after he is pulled from the lion's boxcar. It is also known as a Colt 1873 "Peacemaker".
The German Soldiers in the Castle all use MP40 SMGs as their weapon of choice. Indy takes one from a German Officer and uses it to gun down the German Soldiers that threaten him and his father, he later drops it when Vogel holds Elsa Schneider (Alison Doody) at gunpoint. As the film is set in 1938, this would be an anachronism, but artistic license "could" be claimed by saying they are meant to depict the earlier MP38 (which would be less available as a prop). At least the use of MP28 & MP35 SMGs lends more accuracy than the universal use of MP38/40's in Raiders of the Lost Ark, which was set in 1936.
During the Boat Chase scene in Venice, Kazim (Kevork Malikyan) attempts to use a Haenel-Schmeisser MP28/II to kill Indy and Schneider. Is is also seen with the receiver catch undone.
Beretta Model 38/42 (mocked up as a Villar-Perosa Mod 15)
In the scene where Indy and his father escape the Zeppelin, they are attacked by 2 German fighter airplanes. Indy's father uses a Villar-Perosa Mod 15 mounted on the biplane to try and hold off the fighters, but accidentally shoots the biplane's tail. While the gun is clearly SUPPOSED to be a Villar Perosa Mod 15, the actual prop used was built by mating two upside-down Beretta Model 38/42 submachine guns. This explains the straight magazines and why it really doesn't look too much like a Villar-Perosa.
Another weapon used by the German Soldiers throughout the Film is the Karabiner 98k. K98 rifles are also used by the Cultists that attack the German Convoy.
Previously identified incorrectly as a Karabiner 98k. It differs in its handguard (extends behind rear sight), bayonet lug (located below stock), and forward sling mount (flexible). The K98 has a shorter handguard, bayonet lug between the barrel and the cleaning rod, and a fixed sling mount.
A member of the Brotherhood of the Cruciform Sword fires a Czech vz. 24 rifle at the Germans. Sometimes incorrectly identified in this scene as a Karabiner 98k. It has a straight bolt handle, a handguard that extends behind the rear sight, and two different forward sling mounts, one under and one at the side. That fits the profile of the Czech vz. 24. The K98 does not have any of these features.
A German fighter plane opens fire on the biplane carrying Indy and his father. In reality, the plane was a Pilatus P-2, a Swiss-manufactured training aircraft flown primarily by the Swiss Air Force, but widely seen used in productions as a substitute for German fighters.
When Indy is watching the German column in Hatay, they spot him when the sun glints off of his binoculars (an amateur mistake that Dr. Indiana Jones would probably not make), but when the camera goes to closeup of Indiana, his father and Sallah, the sun is to their backs, ergo, light reflecting off of Indy's binoculars would be impossible.
