More photos of a known Colnago Saronni that has been repainted. People have noted a number of similarities to the Colnago Master frames of this vintage.
Colnago started making budget level frames and went from high end Columbus to low end Tretubi but certainly you have something else. The only thing that says your frame may be a BMZ made for Colnago are the cable guides. Different sort than Colnago used and three instead of two. But BMZ made a lot of frames for a lot of famous marques and very high quality at that.

Also, toward the end of the line Colnago stopped making Saronnis completely and the marque was taken over by Technotrat. I found a couple shoddy photos of a Technotrat Sarroni and there is nothing on the seat stays at the cluster.
Technotrat advert:
I want to thank my buddy Noe. I gave him a ring in Australia and he tipped me off to these photos and the Technotrat connection. I don't want you fellows to think I hadallthis my head. Doesn't seem as if Saronnis were ever marketed in the USA, or certainly not in any numbers, but they are more prevalent on the Continent and some made their way to Aussie.
PS:
Saronni winning the Worlds at Goodwood in 1982 was my first real moment of clarity. So I have a soft spot for all this.
