I have a very similar Marinoni and I got it with no defined pedigree. I did send several clear pictures to Marinoni company, asking for information pertaining to the bicycle.

Mine is either late 1975 or early 1976 and would have been fitted with full Campagnolo NR components with a Cinelli steering stem and handlebars (old logo of course). The rims would be NISI tubulars, laced to NR high flange hubs and the saddle, Brooks "Professional".

The Marinoni "Quebec" (my nickname for the bike) offers a great ride and I have put many miles on it. The bicycle, sadly, had been powder coated by the previous owner but looks so good that I do not have the heart to put it back to original condition.

The pictures I have of the "Quebec" are poor so I will not bore you with them. There are some pretty good shots of the bicycle on Wool Jersey, under the title of Canadian Collector for those who are interested.
