Hello bicycle friends:
Is there anyone on the list who knows the actual dates that each of the many versions of Simplex derailleurs were introduced, and if possible when they were dropped from production? I already checked the CR site and was only able to find '61 as the date of introduction of the Delrin Prestige derailleur.
In particular, I am interested in the chrome plated steel parallelogram derailleurs. I have seen two versions, one with the Simplex logo stamped into the outer plate, and one that has a logo plate riveted to the outer plate. Which came first? Also, I have a couple of variations of the Tour de France derailleur as well. I would like to be able to use this information to help me establish the approximate date of a couple of older Peugeot bicycles.
Any and all help will definitely be appreciated.
Thanks, and happy cycling to all.
