The #90 car is Taruffi's Freccia d'Oro #916602
I think it's worthwhile to add the pictures here before they expire and are lost on eBay. The first picture is from auction #230193979101 "CARRERA PANAMERICANA 1950 Alfa Romeo Bonetto PHOTO", the second picture is from auction #230193979089 "CARRERA PANAMERICANA 1951 Alfa Romeo Panini PHOTO".
This might be important information for Luc Colemont, the author of the "Freccia d'Oro" book and maintainer of the Freccia registry.You are mistaken this time re: the 1950 Carrera Panamericana cars.
#90 is Bonetto/Bonini
#103 is Taruffi/Ceroli
The daughter survived :The 1951 car with the big number 19 on the side is the car that went off a cliff with Panini and his daughter, who was driving at the time. If I remember correctly, both were killed.
This photo shows Taruffi with no90.Yes, I am aware that different sources give different drivers for #90 and #103 and I am not sure which is correct.
BBR makes models of both cars, but no driver's names are on either model.
Here is their model of #90, BBR product number is 11B:
