No one has mentions that frames have date codes stamped into them from the factory. Starting in 1952 Harley stated dating frames. Here are some pics from various frames I am fixing to powdercoat and the models they came from

This frame was manufactured in Dec (J) 1955 (5). This ca,e off Bo's 1956 ST
