Hi, I believe that my Nottingham "Sprite 27" 5 speed (Huret derailleur, Brooks mattress,etc..) is all original and is from roughly 1972. Both of my hubs have the Raleigh logo but I dont see anything about "Sturmey A." My serial # is clearly stamped under the seat lug and is 7 digits w/ no letters. Can anybody tell me if the Sprite should have hubs stamped Sturmey?? Thanks, Mark Steinke Denver,CO USA
