Okay, so I'm breaking my own rules here, but there's a tenuous Italian connection! This is a Marotias, from Eastern Spain, one of the very rarest of bikes available. Normally only found in collections, and almost never resold online. They tend to pass from one collector to another. This one famously with drillium components featuring Super Record and ultralight Zeus Titanium bottom bracket, front and rear hub spindles, skewers and aluminium cassette.
It's a regular Reynolds 531 tubing frame, but silver soldered and the entire bike incredibly only 8.2kg! You'll never see these on eBay. Merckx famously commissioned one to replace his Colnago/Kessels and they also built race bikes for Luis Ocana, Pedro Delgado and time trial specials for Indurain. Merckx rode his Marotias painted as a Colnago, which I suppose him being the star no one would argue with. Allegedly his favourite frame and borrowed the geometry and style for his own Corsa Extra range of bikes.
