These were made from at least 1935 onwards* though I don't think there's any evidence that they were made as early as 1923. The earlier ones had a different style pedal cap with light knurling. Lyotard pedal models were all numbered ­ 460D were the double sided aluminium pedals so favoured by cyclo-crossers for many years. The numbers don't have as far as I can see anything to do with dates unlike some other French bits of kit. The allen bolt/hexagon axles were a pretty late mod ­ probably from the early 80s. The earlier style of axle had two lengths of thread introduced sometime I think in the 70s to be used with either steel cranks (short) or aluminium cranks (long).
      One problem that arose quite often in use was the top flat plate becoming loose or detached from the rest of the body due to the riveting being a bit duff. * There was an ad in Cycling about this time which displayed the wide range of Lyotard pedals available. Hilary Stone
