most of the rubber horn bulb can have the open end opened out using a rough round file. items 617, 618 and CA762 have a removable plug. the rubber bulb should fit to a tube, however on many old horns this is missing and the thread is visible. once fitted (easing the bulb over the tube with wash up liquid helps) the part should fit snugly
