Steamboy is a animated feature film from Katsuhiro Otomo (director of Akira and Memories), and currently the most expensive anime film ever made, with a total production cost of approximately $26,000,000. Set in an alternate 19th-century England, the plot concerns the discovery of a fictional ultra-pure form of water, which inventor Lloyd Steam and his son Edward have realised can be used to create a "Steamball," a device capable of producing almost unlimited power. When a package containing the prototype Steamball and instructions to guard it is delivered to Lloyd's grandson Ray, he soon finds himself being pursued by a group called the O'Hara Foundation who intend to take the ball for themselves. The English voice cast is worth noting, as it includes Patrick Stewart as Lloyd Steam, Alfred Molina as Edward Steam, and Ana Paquin as Ray Steam.
The following weapons were used in the anime film Steamboy:
The Steam Castle has side mounted Gatling Guns manned by crewmen.
The men trying to stop the O'Hara Foundation use the MAS-36 rifle as their standard weapon. Some are modified to fire grenades.
Lloyd Steam uses a Bodeo M1889 revolver.
Unidentified Flare Pistol
Jason, one of the O'Hara Foundation's henchman, uses a Flare Gun to alert another nearby henchman. It looks like a two-barreled pepperbox-type pistol of unknown design.
Alfred Svenson uses a Borchardt C-93 pistol, fired from a crouching stance, to shoot and wound Ray's grandfather.
Several of the O'Hara Foundation's "Steam Soldiers" carry fictional, lever-action grenade launchers.
