[QUOTE=velomateo;8308347]If not Colnago, where did these frames come from? They seem to be around the same year as the Colnagos. /QUOTE]

Velomateo, thats the million...well twenty $ question. I couldn't find those answers either.
The one thing I discovered is the Colnago Saronni's had the club insignia on the frame decals-as per your catalog picture - while our's don't. I don't know if this the only way to distingush manufacturers. The Tipo's I've seen always had fairly low end component packages while the Colnagos generally had Campy NR or SR builds. These Tipos may very well have been built along side Colnagos,who knows? There were probably dozens of factories piling out all kinds of "marque's" back then, I have and old 60's bike badged Norstar, made in Italy and imported into Canada whose lugwork is identical to a Fausto Coppi among others i've seen on these pages.
I've seen very few Saronni's around and regardless of overall quality I think they're pretty cool and mine rides like a dream.

Cheers.
