Midsomer Murders - Season 19
The following weapons were used in Season 19 of the television series Midsomer Murders:
Webley .38 Mk IV
An old-fashioned pistol is seen on the wall of the pub in "Last Man Out" (S19E03). No kind of external lock is visible, so this is more likely not a flintlock or percussion cap gun but a breechloading one. Judging by the general shape, notably by the spur on the grip, the pisotol can be identified as a small caliber parlor gun of Victorian era. Exactly the same looking pistol is also used as wall decoration in Season 21.
Double Barreled Side by Side Shotgun
In "Death by Persuasion" (S19E05) a mysterious person (the character isn't seen with the gun) uses a double barreled shotgun in assassination attempt during Jane Austen style weekend.
Double Barreled O/U Shotgun
Over and Under Shotguns are also seen in "Death by Persuasion" (S19E05).
When Sgt Jamie Winter (Nick Hendrix) disarms Blake Keswick (Christopher Colquhoun), and the revolver falls on ground, it switches to a toy cap gun.
In the opening scene in "The Village That Rose from the Dead" (S19E01) a victim is crushed to death by FV433 Abbot SPG.
