This document, which I think dates from 1978, shows two Gipiemme near-groupsets:

• Special
• Dualsprint, or possibly DualSprint or Dual Sprint

Neither near-groupset includes derailleurs. These came later.

Finally I note the World Championship coloured bands on the cover. I am not entirely clear what these refer to.

Many thanks to Fernando in Argentina for alerting me to the page on the Gipiemme web site that provides these fascinating scans!
