Aneirin -> Rotring anyone ? (12/10/2008 7:24:20 PM)

Does anyone here know about Rotring technical pens, in particular the cartridge fed Rapidograph pens ?
I have one I have been forced to take apart as it is hopelessly blocked, but on taking it apart, I removed the piston weight expecting to find the fine wire nib cleaner on the end, so was being very careful. Out came the piston weight, but no needle attached like the Isograph pens. Can anyone tell me what the crack is with this set up, should it have a cleaning needle attached or is my drawing nib broken ?
To note it is on the 0.35mm size pen nib
