I was able to tell him that I did recognize my own work and that I did indeed build this frame. Points of recognition are: The seatstay caps:
Compare this to this later frame built in California in 1983
The rear drop outs. This was how I finished them at that time
Compare these to this English built frame from 1975
Later after working for Masi I decided the way they finished their drop outs was a more aesthetically pleasing style so all frames built after 1980 were finished like this one.
This fork crown on the Paris Sport frame was forged (Hot stamped from a steel blank, not cast.) and somewhat unique in that I brazed a washer over the brake hole so the brake would have a flat surface to seat on.
The Prugnat lugs and the top tube cable guides I remember using these. Lastly the little round stop under the down tube to prevent the gear lever clamp from sliding down the tube. I went to a factory in England where they did metal stamping and collected a number of 3/16 in. diameter blanks that were left over from stamping holes in sheet metal. They made perfect clamp stops and I brought a number with me when I came to the US.
The frames I built at Paris Sport did not have my name on them. They either had the Paris Sport name or they were sold like this one with no decals or frame number. It is quite rare for one of these to surface and as they had no markings I'm sure a few are laying around unidentified.
