Note:
Letter 'L' after engine lettering or number denotes long shaft model
* = Current production models

  • From 1963 a letter and number code is used at the end of the engine number to denote the month and year of manufacture.
  • The letter indicates the month and year of manufacture i.e. A3 = JANUARY 1963, B3 = FEBRUARY 1963, etc.
  • From 1973 two letters were used in the code to indicate the month i.e. AA3 = January 1973, BB3 FEBRUARY 1973, etc.
  • The letter 'L' is not used in this code sequence.
  • Therefore identification of a model and date of manufacture can be found as follows: WSPCL 1734 BB3.
  • WSPCL indicates this is a long shaft Silver Century Plus. 1734 is the production number and BB3 indicates it was manufactured in February 1973.
