From the 1972 Legnano catalog, if it is of any interest. This is obviously the Italian catalog and I don't no if this spec matches what was exported.
That's interesting info, but several parts don't coincide with what I have and what I know was original, such as the Universal 61 brakes. I suspect there was a bit of variation when they switched from Universal to Campagnolo brakes and when the catalogs were printed. There are a few aspects of this bike that don't jive with the norm, such as the gold lining. I suspect I'll never know 100%.
