Better with pics...

 

Jonneret - 0486M
Daetwyler - 0548M
Wharton - 0514M
Trintignant - 0520M (?). Trintignant was a works Ferrari driver in 1956 so should have had access to just about anything, can we be sure it was a 750 Monza? I was going to suggest #0568M (which Trintignant raced earlier in '56) but that was racing at the Swedish GP the same weekend. The only French owned 750 Monza racing in '56 was #0520M so maybe he borrowed it from Picard?
Magioli - 250F #2515

 

I thought to 0520M too (the Scaglietti spyder S2 on the pic above doesn’t look red) but the Scuderia Ferrari badge is missing on the fenders.

 

I have 0584 M renumbered to 0578 (a 857 Sport), which is unlikely since already regulalarly raced by de Portago)?

 

The 857 S had large side vents. The picture above shows a Scaglietti spyder S2...

It seems that Trintignant was a late entry, as he is not mentioned in the official race program. Does anyone know his race number?

On this screenshot, you can see the side vent is the classic one for a Scaglietti Spyder S2.
On August 1956, 0552M already had large side vents due to a rebody so not this one.

 

Of the 33 750 Monza, at least twelve (#0492M, #0494M?, #0496M, #0498M, 0502M, 0504M, 0510M, 0538M, 0554M, 0562M, 0570M, 0582M, 0586M) were in the Americas, another one in Australia (#0462M). #0524M was in Portugal. #0508M & 0576M had been destroyed. #0526M, 0470M, 0568M and 0518M were all in Sweden for the Grand Prix that weekend, #0486M, #0548M, #0514M were driven by their owners at Ollon-Villars. That only leaves

0440M - French owned and unused that weekend!
0496M - Owned by Alfonso de Portago (fellow Scuderia driver) and unused that weekend!
0500M - Mystery between late '55 and '60s but probably in Sweden
0516M - Believed written off at the Supercortemaggiore in '55
0520M - Owned by Rosier who was a team manager as well as race driver, unused that weekend!
0522M - Almost certainly already in USA
0530M - Italian owned but unused that weekend!
0550M - unknown history beyond April '56 when it didn't appear at the Giro di Sicilia
0552M - Owned by Harry Schell but kept in Europe and not used that weekend!
0578M/0584M - Possibly (unlikely) still owned by Scuderia Ferrari before sale to Whitehead
0584M/0578M - Another of de Portagos cars. Unused that weekend!

Still more likely to be #0520M but could be either of the de Portago cars, more likely #0496M since it was unused at the time with de Portago racing his newly acquired 857S #0584/0578M.

 

Again, you can forgot the 857 S. Their large side vents don’t fit with the pictures above. Same thing for 0552M which had different side vents.
It’s true the car with the closest cockpit design + hood is 0520M...

 

My vote goes for 0520M. Would like to find a confirmed photo of 0520M properly showing that "letterbox type" air inlet in front of windscreen, but yeah: the windscreen setup looks identical, color is right and Rosier's fatal accident 2 months later would perfectly explain why there are no later pics of such a car.

Just before the crash at Montlhéry.
SF badges are missing...

 

If I compare the pic of post #14 with that of post #10, the leather strap to close the hood seems missing?

 

Montlhéry?

Hyères 1955. 0520M was not there.

 

Ah, yes - silly. Several photos incorrectly labelled

Pic around the cockpit of 0520M on 7 October 1956.

 

It’s true Trintignant raced some monoposti and Talbot Lago from the Écurie Rosier the previous years so who knows ?
