One of the rarer sets of freight wagons is the Ausiliare Set from 1990. Ausiliare is a Milano/Italy based wagon rental/leasing company. This set contains five different freight wagons in blue with Ausiliare lettering:
30 2715 4 wheel tanker for liquids
30 2905 bogie gas tanker
30 9048 articulated car carrier (with 4 Fiat 131 cars)
30 2804 twin silo
30 2868 long bogie flat with bulkheads and canvas (sorry, only small picture from my website available)
The bogie flat was the only one in this series to be lettered for SNCF instead of FS Italia.
In the first two years only the bogie flat and the twin silo were available for separate sale, the others came only in the set. After 1993 all models were sold separately. None of these models had short coupling mechanism.
