allow me a little thread hi-jack: many years ago I was a student studying Industrial Design. One of my Lecturers had recently returned to the States after living (and working a little) in Italy, specifically Rome and Milan. He used his recollection of Cinelli to illustrate his impressions of how products were manufactured in Italy. According to him, the culture did not encourage firms to grow large and bring all processes in-house, rather there was a strong independent streak within the skilled trades and many "artisan/jobbers" who would be employed to produce things and deliver piece-goods to the big cheese. His claim was that Cinelli used a bunch of small shops around Milan who could take an order and forge aluminum alloy (more or less) to Cinelli specs, then delivery to Cinelli (or a finisher) for polishing and anodizing...the only thing Cinelli needed do was the last quality check and packaging. He said (and I may have seen examples but can't be sure) that if you compared enough individual stems to each other you could detect variations in the forging marks, the shapes, even the logo stamp placement.
Whether true or not I believed it then and it's still an interesting story.
