So I got in touch with Jim Allen over at Cyclesmiths in Ranchita. He says that it's one of Alberto's Prestige models built in '85. He pointed to the investment cast lugs, and Alberto's signature lower case engraving on the fork crown and seat-stays. He says it was probably repainted at some point by Masi.
Given this information, any ideas on worth? And is it worth more altogether or parted out?
