Maybe you missed it on the CR list Mark, but Italian Masis have a letter for the city it was built in and a size in centimeters c to t stamped on the BB. M60 = Milano 60cm. They usually have a date code stamped on the steering tube; digit for month and two digits for year. Yes, you have to pull the fork out of the frame to find the date code on the steerer.
