Trying to see if there's any sort of discernable pattern to the serial numbers on Frejus road bikes from the early-mid 60's, specifically to determine (as narrowly as possible) the year of manufacture for the project I'm working on. Anyone have data points they could send me? If I get any I'll compile a list and share it with the group.
Or even better, does anyone know how to 'decode' a Frejus serial number?
Thanks,
