What I do not quite understand is where the wedged head comes into this. The David Dye and other specialist heads all benefit from highly engineered improved gas flow as well as increased compression, and the late Ruby head claims better gas flow. But the wedged head has original combustion chamber shape. David, if our railway station was still open I'd hand a spare wedged head over to the guard. After a long passage through the branch lines of wales it would reach you at Bala station in due course.
Today's technical question. When the horn button unscrews itself and falls off, how does one screw it back on? Are there special tools, or an arcane technique involving blu tac or knitting needles?
Most likely it involves unscrewing the clamp at the other end of the steering column to allow the horn push and stator tube to be sufficiently withdrawn to get access to the back of the switch... I may be able to furnish a photo.
