I am still confused about the museum's claims
While I have been thinking about this, I re-read the claim from the Museum about the history of its cars
"This is the actual history of the museum-car:
1973 Le Mans, 14th, Gregg/Chasseuil
1973 pre-training Le Mans, 4-hour race:4th, Schurti/Koinigg
1973 Targa Florio, 3th, Kinunnen/Haldi - source factory museum"
If we assume for the minute that it is car 020 there in the museum, the claim that it was the Schurti/Koinigg car at the Le Mans 4 hour (car #61) does not seem credible. The Picture above that does not look like 588 is car 62 and we can see Van Lennep driving it as he had a very distinctive helmet.
IT seems to be the 020 car which means that the Schurti/Koinigg car would have been R6 (588) the eventual Targa winner now with Peter Kitchak, not the "pretend" targa winner.
I wonder if the claim about the Gregg Sonauto car at Le mans (car #48) is equally questionable, especially given the picture of it soon after Le Mans with the very wide rear wheels on the test track
