Top center candidates are as follows?
P-118 single seat fighter similar in configuration to USA Bell P-39
P-129 single seat fighter developed from P-119 with Daimler Benz DB-605 engine
P-132 single seat fighter developed from P-119 with Piaggio P.XV RC.60 engine
Also I can see some twin engine land aircraft.(Left end No.2 from the top, middle, etc))
Cndidates are as follows?
P-111 twin-engined high-altitude research aircraft of 1938
P-121 commercial transport landplane (8-seat) with two IF Delta RC.35
P-122 twin-engined dive bomber to compete Breda Ba.201
"In 1939, a new contest for a dive bomber was called, requiring a single-engine aircraft with a maximum speed of 500 km/h (310 mph), or 450 km/h (280 mph) if twin-engined, capable of carrying 500 kg (1,100 lb) bombs, with an endurance of 1,200 km (750 mi) with a single engine, or 2,400 km (1,490 mi) with two engines.
There was only one twin-engine proposal, the Piaggio P.122, which despite its all-metal construction, dorsal-wing airbrakes, two Piaggio P.XI R.C.40 engines giving a total of 1,491 kW (2,000 hp), and the lack of competitors, was considered unfit for service and was unbuilt.
Two single-engined types were proposed, the Caproni Ca.355, a single seat derivative of the Ca.335 light bomber that first flew in January 1941 and the Breda Ba.201."
