Boulton Paul Bugle
The Boulton & Paul Bugle was a heavy bomber designed and produced by the British manufacturing group Boulton & Paul. There were two variants; the Bugle I with 400 hp (298 kW) Bristol Jupiter II radial engines (five built) and the Napier Lion W-block Bugle II (two built) == Development == Work on what would become the Bugle effectively commenced at Boulton & Paul following the Air Ministry's release of Specification 30/22, which sought a new twin-engined heavy bomber to equip the Royal Air Force (RAF).
