Hmmm...so those blue "Bottecchias" that were ridden by Gianni Motta and the Molteni guys in the mid-60's and the later blue "Molteni" bikes of the late 60's that look pretty much identical save for decals and head badge might not have been build by Ernesto? They don't resemble the later Colnagos. I always thought those were built by Ernesto and the later factory Colnago branded bikes perhaps weren't.
