I came across a red one, quite similar to the one the OP has pointed out about 7 or 8 years ago. It was set up as a city bike. It had a dog's breakfast of parts, some pretty nice, some quite pedestrian from different sources. Pretty sure the tubing wasn't anything special, as there wasn't a Reynolds or Columbus sticcker on it. I never pinned down the date (I figured 60' or early 70's). I took the bike to Cirque and put it in the charity auction. I think it went for $135.00
