Just bought this little number. It was ridden one season then stored. Still has original tubular tires on it. It was originally bought at Oak Bay Bikes, Victoria BC in 1983. Dura-Ace EVERYTHING. The person I bought if from said it weighs 19.3 lbs. I still have to verify that myself but its amazingly light. I know from the cereal number its an 81, made by kuwahara, Osaka Japan. From the research iv done my best guess is its an Imperial.
Any info or comments would be much appreciated
