Barb's motorcycle is a 885cc Triumph Thunderbird made as a water-cooled three cylinder model by the new Triumph factory at Hinckley in Leicestershire. In later scenes she rides a Triumph Tiger which also had an 885cc water-cooled three cylinder engine.
In one scene, Barb is using some glasses which inform her that Krebs is in the room next door. She has them on her head, but in the very next shot they are suddenly in her hand.
In the opening scene, when Barb is dancing, her nails are bright red. When she goes back into the dressing room after the dance her nails are French manicured.
