Raymond Worrall's (Benjamin Fisher) Smith & Wesson Victory Model, identified by dull grey parkerized finish, plain wooden grips and lanyard ring, is the murder weapon in "The Eagle and the Daw" (S05E06).
In "The Sins of Others" (S05E11) Sid Carter (Alex Price) owns an illegally purchased snub nose 6-shot revolver. In some scenes Penelope "Bunty" Windermere (Emer Kenny) and Lydia Reese (Susie Trayling) briefly hold Sid's revolver. The gun looks S&W style, with thumb cylinder release, unsupported ejector rod, large grip with lanyard ring, but lacks front sight. A possible guess is a standard Smith & Wesson revolver, like Military & Police Model that has the part of the barrel with ejector rod socket sawed-off.
In "The Sins of Others" (S05E11) the assassin, credited as "Panama Man" (James Sutherland), uses a rifle with sniper scope and sound suppressor. It is possibly some version of Mauser 98 Sporter.
