I think I have the same model - though I am not sure it is am "International". Bought mine new in summer 1981, with my first pay check after graduating university (actually it took my first 2 paychecks - and cost me $1100 if my memory serves me). To my eye its lovely bike and is still great to ride, though as I prefer a more upright geometry now that I have aged, I'm new to the forum and will post pics if/when permitted. The code on the bottom bracket is KI 20447. Can anyone tell me more? Other features of my mostly original bike - 10 speed with SunTour Cyclone derailleurs, down tube Suntour shifters, Sugino Super mighty crank, Dia Compe brakes...
