Helicoil would be the usual fix for stripped threads. That or drill and tap to a larger screw thread. Not sure you've got much space on that little nub on the head tube though. Failing that weld or braze the hole up and retap.
yeah I basically need a decent mechanic that knows bromptons and one end of a helicoil from another...
