I only want to state, that the picture is not from 1965, but for sure from 1964, before the Le Mans race in June 1964, showing CSX2299, the first Modena-built Cobra Daytona Coupe.
Together with the first ever (Shelby-American-) built Daytona Coupe (CSX2287), CSX2299 went to Le Mans 1964 (see attached picture on the Italian-French border).
CSX2286 followed ready for Goodwood 1964, and had the same altered roofline as CSX2299, which makes these two 1964 Daytona-Coupes distinctive.
The three other Daytona Coupes (CSX2601, CSX2602 and CSX2300) were built in the off-race-season and completed by February 1965, for the Daytona-race.
Thank you so much for the point. Very nice puzzle!!!
