A good reference for this would be the Filipinetti book of Ed Heuvink. The team's history and the Parkes link would suggest it a likely thought. The book did not mention it I believe.
.
Indeed a good reference and I can confirm Heuvink does not mention it at all. He writes about the sport-prototype program:
" The prototype program for 1973 would be in line with the previous year. A two-liter Lola, model T292, would be used for the European two-liter championship and some French events. Two cars were entered for the 24-hour race in Le Mans. Jean-Louis Lafosse would be partnered by Gerard Pillon. Lafosse was also to drive the three-liter Lola T282 in all major World Championship events. The car would be colored blue, promoting Gitanes cigarettes. For these races Lafosse was to be partnered by Reine Wisell, and on some occasions Hughes de Fierlandt."
So, no trace of Ferrari, March, Elford or Lauda. The only March-BMW that appears in the story was the F2 car where since the Scuderia had no money to buy it (Heuvink dixit) it was bought by sponsor Antar and run by Filipinetti on its behalf. If Coulon run a March in 2-Liter racing, which I have no recollection, it was certainly not for Filipinetti.
