I finally had a chance to get it cleaned up, lubed, and road worthy, and I put on some 700c wheels and took a spin. For a bike with the steepest angles and tightest geometry of any I have, it rides very nicely. Stable and not twitchy at all. The headset and BB were in surprisingly great shape (now re-packed), and the paint actually cleaned up fairly well, though it'll never be a beauty queen, and the chrome is history. I can just make out the "Coppi" logo shadow on the downtube. At this point I plan to get a decent saddle, bar tape, cable clamps, trim the brake housing, and just ride her as-is.
