I believe the Stronglight 49 was introduced in 1949. I have a mid 50's Peugeot with a similar arm mounting (5 bolts close to the arm) but it is steel and cottered. I believe this is a 55 Competition model, then came the model 57 "Super Competition", then the model 63 "Super Competition", then the model 93. I have a parts catalog from the late 70's (c. 1977-78) that shows the model 49D as an option, with the model 105 bis as the top of the line.
