From Graces Guide
Note: This is a sub-section of Boulton and Paul.
1926 Day bomber. Twin-engined three-crew biplane powered by two 460 hp Jupiter VIIIF engines. 18 aircraft produced but four were converted to its successor the Overstrand.
The Sidestrand had three open gun positions; nose, dorsal and ventral. There was usually a crew of three; pilot, nose gunner and a gunner for the dorsal or ventral positions, the choice depending on where each aircraft flew in a formation. Armament for each position was a .303 in (7.7 mm) Lewis gun, the gun being moved between the two rear positions as required.
It was powered by two Bristol Jupiter VIIIF 9-cylinder air-cooled radial engine, 460 hp (343 kW) each.
