Hi,Hi,I’m a newbie here,Came across your topic what is NS and US are these letters followed by #stamped on seat lug? Thank You
The frame number stamped into the seat lug seems to be an earlier form , they later moved to the left hand rear dropout. The first letter changes whereas the letter S seems to be common on lots of bikes despite the year. I have found a couple of earlier exceptions.
I have based my dating on my two models the Red Feather and Double Blue. The Campag Gran Sport stopped being used in 1963 which I think equates to the letter N on the Red Feather and the Double Blue was last made in 1963/64 which would be U. I think that by using 2 letters per year and excluding O and Q you can get a rough idea of the age of the bike . Well that's my theory.
