Harold Shulman (Michael Parks), the second-in-command of hijackers, is armed with Smith & Wesson Model 19 revolver with a six inch barrel. In several scenes he changes it to SIG P210 pistol and back.
A Webley revolver is seen in hands of Rufus Excalibur ffolkes (Roger Moore) when he is preparing his bag for a trip to London. It is hard to identify the revolver for sure but most likely it is Mk VI.
When Rufus Excalibur ffolkes (Roger Moore) went to negotiate with the hijackers, he had a pocket pistol hidden inside his naval cap. This pistol is a Spanish Llama Model XVIII .25 calibre pistol.
