To complete this for future reference of others.
Robert Foreman very kindly sent me some new condensers - one of which I fitted. This made no difference, unfortunately.
Stuart Ulph suggested a chaffed wire from the coil - this was checked and found to be fine.
Robert spoke with me and suggested the points - bingo! The pin that holds them had worked loose and was wobbling. Tightening this, along with some thorough cleaning of the points themselves, has cured the problem entirely.
Thank you for everyone's help, Forum at it's best once more.
