A colleague in Italy finally resolved the mystery around the two numbers that Legnano stamped on the seat lug when the actual serial numbers on the seat lug ended in mid 1966. In the photo at the top of this thread the number '10' represents the production from the first quarter of 1970. '26' referencing the second quarter of 1966 is the earliest marking that has surfaced and '13' representing the first quarter of 1973 being the last found so far.
