Isn't it just a frame and a bunch of components???
Possibly a bit off-topic, but, in my opinion, almost any classic Italian road bicycle is merely a frame plus its bolted-on components, right? Don't flame me, but I certainly invite others who were also around in those days to correct me (I was active in cycling and triathlons in the late 1980s and early 1990s)...I believe that many frames were sold by stores without components attached and riders selected the Campy, Cinelli, Modolo, Regina, Sachs and (gasp) Shimano components they desired, or had laying around, some possibly from other bicycles.
Alternatively, I also beleive a shop would have a bunch of new groupos in inventory and purchase a range of similar frames and build them up for display and sale. Or, a shop might have purchased a group of last year’s frames on the cheap and installed slightly newer components (I still own and regularly ride an old Bottecchia which I believe is a product of one of those efforts…on the day I bought it in 1990, there were ten virtually identical Bottecchias lined up at the store, all the same color (red, of course), of varying frame sizes, and basically the same mix of Campy components (Croce D’Aune, Chorus, and Athena)…I still have the receipt and I remember they eagerly offered to swap out any component if I didn’t like the way they had assembled them). Indeed, if you look at some of the old catalogs, they advertise that many frames could be purchased separately or built up with a range of components groups.
FWIW, I don’t strive to locate a bike that’s precisely as it was assembled by a local shop in the 1980s…I do keep the component vintages within spitting distance of each other and the frame. A lot can happen to a bicycle in twenty years (i.e., component swapping, painting, etc)…so, depending upon what your intentions are and how much you know about these old rides, you might post a few photos of your bicycle, and members will opine on how accurately the components match each other and the vintage of the frame.
