Campion is a British detective TV series based on the novels by Margery Allingham. The plot is set in 1930s. Albert Campion (Peter Davison), an aristocratic amateur detective and adventurer, solves the problems of people from high society. He is aided by his manservant, former burglar Magersfontein Lugg (Brian Glover). The first season aired in 1989, and the second in 1990. Eight novels were adapted, each of which was broadcast as two separate hour-long episodes.
The following weapons were used in the television series Campion:
Albert Campion (Peter Davison) draws a Smith & Wesson Mk II Hand Ejector revolver from the suitcase in "Look to the Lady: Part 1" (S01E01). The revolver that Campion uses in the night scene in "Police at the Funeral: Part 2" (S01E04) looks similar to the one used in "Look to the Lady" and possibly is the same model or even the same prop reused.
Smith & Wesson Military & Police
Albert Campion (Peter Davison) holds a Smith & Wesson Military & Police revolver in "Sweet Danger: Part 2" (S02E02). He gives the revolver to Amanda Fitton (Lysette Anthony) who in turn passes the gun to Guffy Randall (David Haig). A Military & Police revolver is also used by Albert Campion in "Flowers for the Judge: Part 2" (S02E06).
Webley .455 Mk VI
A nickel plated Webley .455 Mk VI is used in "Police at the Funeral" (S01E03/E04) for the suicide staged as murder. What appears to be a Webley revolver, very likely a Mk VI, is seen in hands of a British officer in the final scene in "Sweet Danger: Part 2" (S02E02).
Pistols
M1911-style Pistol
When Campion's car is stopped on the road by the gang in "Look to the Lady: Part 1" (S01E01), Natty Johnson (Alan Cody) threatens Campion with a pistol that is supposed to be an M1911 or M1911A1.
Beretta M1934
A compact pistol with typical Beretta open-top slide is used by Brett Savanake (Iain Cuthbertson) in the climactic scene in "Sweet Danger: Part 2" (S02E02). The pistol is seen only in the darkness but what is seen allows to guess that this is a Beretta M1934.
Unidentified pistols
Alistair Barber (Robert Robinson) uses a pistol in the climactic scene in "Mystery Mile: Part 2" (S02E08). The gun is seen only in darkness.
One of Savanake's henchmen holds a pistol when the gang stop the car in "Sweet Danger: Part 2" (S02E02). The pistol is seen very briefly and unclear; possibly this is an M1911.
Submachine Guns
Thompson Submachine Gun
Three of Savanake's henchmen are armed with Thompson Submachine Guns in "Sweet Danger: Part 2" (S02E02). All Tommy Guns have drum magazines and foregrips so they may be M1921A/AC or M1928.
Rifles
Lee-Enfield No. 1 Mk III
In the final scene in "Sweet Danger: Part 2" (S02E02), when a unit of British army is summoned against the gangsters, a Lee-Enfield No. 1 Mk III rifle is seen in hands of a soldier.
Shotguns
Double Barreled Shotgun
Swithin Cush (Geoffrey Bayldon) commits a suicide with a Double Barreled Shotgun in "Mystery Mile: Part 1" (S02E07).
Other Weapons
Mills Bomb
'Squire' Mercer (Nicolas Chagrin) produces a Mills Bomb in the climactic scene in "Dancers in Mourning: Part 2" (S02E04).
Smoke Bomb
Albert Campion (Peter Davison) uses a canister-type smoke bomb with a match cord during the liberation of Biddy Pagett in "Mystery Mile: Part 2" (S02E08). The body of the smoke bomb has markings "W.D. MK VII 8/15". "W.D." means "War Department", so this must be a military piece but the exact model is unknown.
Spray Gun
Alistair Barber (Robert Robinson) uses a spray gun, loaded with strong acid or alkali, in the climactic scene in "Mystery Mile: Part 2" (S02E08). The spray gun is constructed from a syringe mounted on a pistol grip with a trigger mechanism that drives the piston.
