Thanks for the help on and off the List with advice about this dubious Colnago.
I think the advice erring on the likelihood of this being something else badged up "COLNAGO" is probably on the button. I have scrutinised the pictures very closely and note that the ends of the chain and seat-stays are "domed" - certainly not a finish that I have seen on Colnagos and not even on the house's cheaper brand COLNER"
Additionally there appears to be three brake cable eyelets on the top-tube..while Colnago used only two in the early to mid 70s.
Pity really...but I think I will give this one a miss, which is possibly just as well because one List member is showing a serious interest in the 1903 racing bike, which is to be collected not too far away from the Colnago.
Thanks again
