A promising design, the Peregrine never entered production as the company was preoccupied by fulfilling orders for other types to the RAF.

[1][2] The M.8 Peregrine was powered by two de Havilland Gipsy Six series II piston engines, each producing 205 hp (153 kW).

It was equipped with two 40 imp gal (182 L) fuel tanks in each wing, giving it the range of 550 mi (890 km; 480 nmi).

The M.8 Peregrine showed great potential and attracted much interest, but Phillips & Powis (the manufacturer) has just won a contract to build Miles Magister trainers for the RAF and no capacity existed for the manufacturing of the M.8 Peregrine, so it never entered production.

The tests proved promising, with a marked decrease in drag and a 29% increase in rate of climb, but the outbreak of the Second World War halted the research.
