No, no, no. It's Raysport, which was a good SC clone made in Mexico during the mid 70's. They copied all the style points, fastback stay, drilled lugs, Cinelli crown. But a bit shorter and steeper geometry, and Campy vertical drop-outs in the rear.

Actually a really nice frame for the money. And even as poorly finsihed as some of the original SC's! (said with a smile).
