It's the 1946 Sport model, or if it's alloy (I can't tell from the photos) it's the Sport Luxe. The pre-war Grand Sport was similar, but the upper jockey wheel on the earlier model was toothed, instead of a roller, and had no cage. (I obtained this information from Gordon Selby's excellent "History of the Super Champion Osgears" in the Spring 2000 issue of the Veteran-Cycle Club's "boneshaker").
