and maybe this designer Preti had anther Projects ?.
Doubtless. One unbuilt Preti project mentioned under Designations was the 1945 CVV 8
Linate (named after the Milan Linate Airport). The CVV 8 was later re-applied to the
Bonaventura sailplane ... perhaps the
Linate was to have been a sailplane too?
Lots of built designs too. There was a range of built CCV single-seat gliders - the 1937 CVV 1
Pinguino and CVV 2
Asiago designed with Maurizio Garbell; the CVV 3
Arcore; the 1939 CVV 4
Pellicano designed with the brothers Leonardo Venturini and Pietro Venturini; the 1939 CVV 5
Papero and the CVV 7
Pinocchio (designed by Preti in 1940 but not built until 1952) - and 2-seat gliders - the 1942 CVV 6
Canguro and the above-mentioned 1957 CVV 8
Bonaventura.
After a turn at Milan's
Istituto di Ingegneria Aerospaziale, Preti moved on to Isetta in the early '50s, designing the
Iso mini-car. Preti continued to design aircraft too.
In 1949, the prototype P.110 4-seat light aircraft flew. At the time, the design was associated with Aeronautica Macchi (I presume that Macchi built the prototype?) but aka Politecnico P.110 (after CCV). In 1951, the P.110 became the Agusta CP.110 with 145 hp Alfa-Romeo 110 inverted-four which led to the Agusta AP.111 with HO4 engine. I assume that the Agusta P.112 4-seater project was an AP.111 derivative with a tricycle undercarriage.
An unbuilt Preti project for Agusta was the twin-engined AP.100 feederliner.

Another built design was the one-off racer PM.280. I suspect that the 'PM' is for Politecnico di Milano.
