Late 60s/early 70s AO-8 I have had since 1973 (recently posted this same photo in Green Bikes)....This bike has gone through innumerable iterations over the years: it was my platform to build a true racing bike in the early 70s (as I could afford component upgrades I did them, including things like lacing tubular rims to the original hubs and converting the wingnuts to quick release), until ultimately replacing the frame with a proper english racing frame in glorious 531DB throughout (Wes Mason), Since then this has been repurposed as an upright bar tourer, a 3-speed runabout, a 3-speed racer and finally a semblence of its former self. Always a sweet ride.
