Just to update the age issue on my frame, in looking at an earlier Medici thread, number6 made the comment that thearly medicis used "liberated" masi lugs before they "borrowed" the Confente lug design. If so, that would explain the lugs on my frame which do not match the design shown in the Medici catalogues and in other photos of Medicis I have seen. They do match the '76 Masi lugs shown on B Hovey's website.
Although number6 doesn't say how long Medici used the Masi lugs, since they are not shown in any Medici calogues, I assume it was not long. At this point I'm guessing my bike is a '78, perhaps the 101st built ?
Thanks again, d
