My next step is based on the map. Car #50, the Ermini coupé identified by SACO, seems to have been placed next to a corridor separating the Lombardi / Frua sector from the one situated in the south-east (upper right) corner of the hall. I think I found a picture of that area; if my deduction is correct, the car I highlighted a Moretti 1200 Gran Turismo? was standing not too far away from the Ermini.
