Thanks for the input guys.
The shimano theory sounds spot on gary and I will test the reverse brake theory peugeot mongrol - good idea but never saw a super with crimps only mexico so the super decal is puzzling.
My ignorance made me me always associate campy with Italian and colnago. However, I do have an Ijsboertje colnago colner (Belgium team second colnago mark to get around race rules) which is fitted with arabesque group and also a NOS original gios torino 1979 coin model fitted with super record campy but the headset is arabesque. I found a second gios 1979 the same in need of restoration also with arabesque headset so it is not a swap, it happened!.
I never really associated shimano arabesque/arrow as racing quality but that is my shimano ignorance and campy preference.
I measured the chain stays on the pink colnago versus a colnago nuovo profili mexico
They are thinner ... LHS 13.53- 13,97mm (pink) vs 15.58-15.53 (nuovo mexico). At this time 82 colango was experimenting with the cx aero if I am correct. Thus stream lining was in focus. I do know someone with a vintage cx aero must look at chain stays.
Does anyone know when was the first colnago ESA or masters was released? I think the 80-85 year theory fits (crimping era and ESA MEXICO masters ?)
Gary I will ask my restorer friend Ian de costa in England to draw up replica decals he is a master at colnago vintage frame restoration and reproducing colnago decals. Not that i am not patient but with 4 young kids time is short ...lol
I met up with him at Dressel. He is restoring a colnago ESA mexico frame for me.
I plan the bike to use as my vintage ride for the vintage steel rides here in holland. I am proud and fortunate to have such a colnago bike in my collection
My normal ride is a koga myiata gran lux with C record ergo shifters. Bikes get stolen here in holland !
