This Churchill frame is fitted with the Stallard long point rear dropouts. The long curved horns were first used as far as I know by Super Champion on dropouts designed for use with the Super Champion Osgear - there were several variations but at least two were essentially vertical dropouts. Both Claude Butler and Stallard then copied the idea of the long horns on pure horizontal dropouts...
