[1] Only one was built to order of the Air Ministry, first flown with three-engines, later changed to two then back to three engines.

[2] Handley Page's design to meet this requirement, the Hamlet, was a high-wing three-engined monoplane with a conventional landing gear and room for six passengers.

The wing was fitted with leading edge slots and flaps to give good landing performance.

It was first flown on 19 October 1926 powered by three 120 hp (90 kW) Bristol Lucifer IV three-cylinder radial engines.

[5] In March 1928 it was re-engined again with three 150 hp (112 kW) Armstrong Siddeley Mongoose five-cylinder radial engines although it flew only once in that configuration on delivery to the Royal Aircraft Establishment at Farnborough.
