Melvyn's badges are good ones - the Dragon is a good one!
i replaced my Union Flag ones with his - bonnet was drilled so an easy swop.
Double sided tape is a good alternative and a good finish with cut off screw heads adds the final touch.
If the badge has a curve then someone I know flattened them a bit by sanding the ends a bit - bending them could crack the enamel so not reccomended.
