The Magni Vale PM-3-4 was an Italian civil monoplane for use as a tourer or aerobatic trainer designed and built by Piero Magni-Aviazione in Milan.[1]

Design and development

The Vale was a sleek single-seat parasol wing braced monoplane powered by a 130 hp (97 kW) Farina T.58 radial engine.[1] An improved variant, the Supervale PM-4-1 had a 140 hp (104 kW) Fiat A.54 engine.[1] The start of the second world war halted design and development by the company.[1]
