The Pathfinder (Sledopyt) is a Soviet 1988 (filmed 1987) adventure movie directed by Pavel Lyubimov. The movie is a screen adaptation of the novel "The Pathfinder, or The Inland Sea" by James Fenimore Cooper.
The following weapons were used in the film The Pathfinder (Sledopyt):
Percussion Cap Pistols, out of time for 18th century, are used by the commandant of British fort Major Craig (Emmanuil Vitorgan) and retired Royal Navy boatswain Charles Cap (Georgiy Yumatov). Massive brass nose caps make these pistols look similar to Austrian Augustin models but some details differ.
Muskets
Pathfinder's Musket
Natty Bumppo alias "Pathfinder" (Andrejs Zagars) carries a long musket. The gun has military-style buttstock with brass patchbox, short hunting-style stock and ramrod fitted under the barrel. The ignition system is unclear: the gun seems to have a flintlock (without flint) but when it fires, the action looks more like percussion cap. Also it's impossible to say if this musket is rifled or smoothbore. Despite of its origin, the screen gun is a good reflection of Bumppo's "Killdeer", as it is described in original novel.
Sanglier's Musket
In one scene the French agent Marquess Sanglier (Andrey Mironov in his latest movie role) carries a Flintlock Musket, a hunting gun rather than military. This gun doesn't fire on screen.
Craig's Musket
Major Craig (Emmanuil Vitorgan) carries a musket with out of time percussion cap lock and elements of flintlock. Possibly this gun was originally a flintlock, later converted to caplock. Like Sanglier's musket, Craig's gun also has a short hunting-style stock.
Jasper Western's Musket
Royal Navy Midshipman Jasper Western (Igor Rogachyov) carries a musket that also has a percussion cap lock and elements of flintlock but his gun is long and has military-style stock. Most British soldiers are armed with same looking guns.
Trivia
Cannons
The sail cutter Scud is armed with several muzzleloading cannons. A cannon is also seen in British fort.
