I found something about one of the two cars built by Scuderia Milan on Fiat 1100 B chassis and Bertone body; I understand that one of the two was built for Mr. Ruggeri and the other for Nuvolari. The Ruggeri's car has been destroyed in its second race, while the Nuvolari's one is said to be the #279904 that now has been modified in the front, carries the plate number PS 8945 and has an Ermini 1100 engine.
