The Lost World is a 1925 B&W silent film, a screen adaptation of the famous novel by Arthur Conan Doyle, directed by Harry O. Hoyt and starring Wallace Beery as Professor Challenger, Lewis Stone as Sir John Roxton, Bessie Love as Paula White, and Lloyd Hughes as Edward Malone. This is the first of a number of The Lost World films and TV series.
In 2017, the film underwent a major restoration, for which fragments were collected from various sources, since the original nitrate copy has not been preserved. The film is currently in the public domain and can be watched online.
Note: various fragments of the movie are colorized differently - greenish, yellowish, blueish. The reason of such colorizing is unclear.
The following weapons were used in the film The Lost World:
During the expedition, Sir John Roxton (Lewis Stone) carries a Webley Revolver. Judging by the size, barrel length and the shape of the front sight, the revolver is supposed to be a "WG" Army Model but this is not for sure. Major Hibbard (Charles Wellesley), the head of the Geodetic Survey expedition, carries a typical Webley holster. In the final scene when the Brontosaurus breaks free and causes havoc in London, police constables hold revolvers that are also supposed to be Webley models.
Unknown revolver
Professor Challenger (Wallace Beery) also carries a revolver in holster. He never draws the gun, and only a small part of the grip (ivory or pearl) can be seen. Its shape allows to guess that the revolver may be some Smith & Wesson top-break (like New Model No.3) or early swing-out cylinder (like .32 Hand Ejector) model.
Pistols
M1911
Professor Summerlee (Arthur Hoyt) carries an M1911 pistol. At first the pistol is seen in holster, and later the holster disappears, and Summerlee carries the pistol tucked into his belt. In the final scene when the Brontosaurus causes havoc in London, a man saves a woman from below the giant's leg and fires a pistol that is also supposed to be an M1911.
Luger P08
Edward Malone (Lloyd Hughes) carries a characteristic holster for Luger P08. He never draws the gun, and only a small part of the grip can be seen.
Rifles
Winchester Model 52
During the expedition, Sir John Roxton (Lewis Stone) and Professor Challenger (Wallace Beery) are armed with Winchester Model 52 rifle (funny that Sir John calls this .22 caliber rifle an "elephant gun" which would be true according to the plot, but does not correspond at all to what we see in the film).
Krag-Jorgensen
In the scenes when Sir John Roxton (Lewis Stone) and Professor Challenger (Wallace Beery) fire their guns, one or both Winchester Model 52 rifles switches to a Krag-Jorgensen Model 1896 or 1898 rifles.
