There was no frame identification for purpose of ownership on 1957-1969 model Sportsters.
However, there were stampings on the different parts of the frame combined with certain features that can be used to date the frame.
Click Here to view Ironhead Frame Identification in the Sportsterpedia.

The only numbers for the purpose of identification were on the engine case.

• For 1957-1961 models, the engine serial number is stamped on the left side of the engine case between the two cylinders.
  First 4 or 5 digits are the year and bike model followed by a series of 4 or 5 numbers that established the individual serial number for each bike.
