I've done a lot of searching online and it appears a Milano 7-speed in white is kind of a rarity. The only other model I've seen with the same paint scheme is the Milano Parco, which is a 3-speed:

Based on the serial number the LBS thinks it's a 2000 model. It has a shop sticker from someplace in the Bay Area, so it spent part of its life in California before coming up to Oregon. A shame somebody took out the stock crankset and fenders. Picked it up off Craigslist instead of a new 120th Anniversary edition in silver.
