It sounds as if the bolt is seized and the vent has become unscrewed from the bolt. To get at the bolt head means, as you have worked out, getting the internal casting off. This is secured by the top glass retaining screws, which tend to get well stuck, and may need heat and other means of persuasion to get them out. (Probably followed by drilling and tapping to fit new ones :-( ) You might be able to get the vent to close by applying WD40 to the bolt,with the vent off, and screwing the vent back on hard. With a bit of leverage on the vent, this should shift the bolt in a bit. However, the bolt will remain partially seized, and when the vent is unscrewed, it will most probably come off the bolt, rather than the bolt moving in the door as it's supposed to. For the complete cure, the inner casting has to come off, the bolt freed off in the door and the vent replaced and tightened with a spanner or socket on the bolt head and the vent held with a lever of some sort beween the operating lugs. Hope that makes sense, -- Iain
