Lupin III: The Fuma Conspiracy
Lupin III: The Fuma Conspiracy is a 1987 original video animation (OVA) film directed by Masayuki Ōzeki, and the first OVA in the Lupin III anime adaptation. Because of its lower-budget production, it is the only Lupin III media where the original VA cast and composer - although available - were not featured. This unfortunately put a rift in the friendship of Yasuo Yamada (the usual VA for Lupin until 1995) and Monkey Punch, the creator of Lupin III.
The plot revolves around the kidnapping of Ishikawa Goemon XIII's fiancée by the Fuma ninja clan in return for a valuable urn heirloom that discloses the hidden location of a vast and forgotten treasure. Lupin and the gang assist Goemon in not only returning his bride-to-be Murasaki back safely, but also taking the treasure for themselves!
The following weapons were used in the anime film Lupin III: The Fuma Conspiracy:
Lupin carries his trademark Walther P38 pistol throughout the movie, but only uses it during the train turntable scene.
Inspector Kazami fires a Walther PPK at Lupin outside the police station.
Inspector Koichi Zenigata carries his usual Colt M1911A1.
An unidentified pistol, visually similar to the Colt Pony, is inside the box that Fujiko tosses to Zenigata during the car chase.
Several police officers have holstered pistols, but they're too indeterminate to tell exactly what they are.
Smith & Wesson Model 19
Daisuke Jigen carries his trademark Smith & Wesson Model 19, but never actually uses it.
Several of the Fuma clan ninjas use IMI Uzis at the train turntable exchange.
Old Man Suminawa (Kōhei Miyauchi) carries an indeterminate double-barreled side-by-side shotgun in several scenes.
Many gold-plated Tanegashima muskets are stored in the treasure castle, some of which Jigen tries to take.
Keeping up with the old-fashioned theme, the Fuma clan ninjas use era-appropriate crossbows.
