The Man from Marseilles - S5-E20
Continuity mistake: While Carol has Fornier and Magnum in her office, Fornier explains he's just visiting as a tourist and she responds that he's illegally carrying a gun. In the next shot of Carol's torso there are changes which include, Carol's ring is missing from her left hand, and in this shot her blouse has buttons though there shouldn't be any, etc. (00:20:25)

Visible crew/equipment: When Magnum picks the lock of the stateroom so he and Carol can enter, in the next shot of Fornier with the syringe, the camera zooms out and lighting equipment is visible at the right side of the screen. (00:43:45)
