Oh, another thing about Colnago. Early Colnago Supers had some kind of a paint transfer method. Someone described it, but I lost it. By the late 70's or early 80's, Colnago switched over to some really ugly decals. Then into the 90's, they returned to paint.
If the bike has been repainted, chances are that someone stuck decals on it. Some decal work is of excellent quality. Some is of mediocre quality.
