I found an old maintenance manual for this interesting engine built in Italy in 1930. 2 versions were made, one aeronautical, aluminum casing, one for naval use, all cast iron.
It's a very challenging project but I decided to build the airplane version, 1: 5 scaled engine model, I think it is a 6 cylinder engine multiplied 3 times, I hope to be able to make it work.
Technical features:
Bore =140 mm( 5,5 ")
Stroke=170 mm(6,7")
Displacement = 47.100 cc (2874 cubic inch)
Power Hp = 924
Some photos and drawings taken from the manual:
