Classic way of frame building, even before blowtorches were commonplace or widespread.
Frame and lugs were pinned with pins prior to the brazing above a coal forge / coal-fired furnace "a base di legno dolce" literally on basis of sweet wood - Weichholz, therefore no frame jig could be used.
Build for F. Gimondi early in his career, as José Manuel Fuente (record holder ;-) four consecutive times
