This frame was the second one I built for myself in June 1977. Like the Gold one I used the parts on it for my next frame (the pink bike I rode at the Eroica in Paso Robles - http://brucegordoncycles.blogspot.com/2015/01/the-first-of-series-on-bruce-gordons.html)
It was the first one I built that had a fixed seat post/seat tube.
I made a steel version of the Campagnolo Seat Post top that took the 2 bolt pieces from a Campagnolo seat post. The seat tube was an .035 4130 Chromoly tube that went from the Bottom Bracket to the Seat Post clamp. I could not adjust the Seat height, but, it was Cool.
It was Columbus SP tubing except the Seat Tube and had Cinelli Stamped Steel Lugs. This is the first bike I built myself that had the Graduated Asymmetric Holes in the lugs. That is a design I still use on many of lugged bikes
