There was no frame identification on 1957-1969 model Sportsters.
The only numbers for 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.
