Not sure, but here's my 1980's ? Bridgestone Highspeed. Some differences compared to yours. The fork tips and drop off front wheel seem to be typical Bridgestone features. This one has 27" wheels and glides so nicely. I really enjoy in on the flats. Hill climbing is somewhat cumbersome with the old style gear levers (Suntour), but I guess my newer Bianchis make it seem so much easier when climbing the steep hills around these parts. OH ya, I picked it up some 12 years or so ago for 22 bucks. Bought new tires and tubes, bottle basket and computer. Oh ya, can't find the original pedals right now, but I know they're somewhere in my garage. Everything else is original. I can't part with it.
