Following their experience with the Bourges and Bugle twin-engine biplane bomber prototypes, Boulton & Paul desighed a new aircraft to meet Specification 9/24 for a three/four-seat medium day bomber. The first of two Boulton & Paul P.29 Sidestrand Mk I prototypes flew in 1926, and the company received an order for 18 production aircraft. Deliveries to the newly re-formed No. 101 Squadron at Bircham Newton began in 1928, the first batch of six aircraft being of the Sidestrand Mk II version with ungeared Bristol Jupiter VI engines. These were followed by nine of the Sidestrand Mk III versions with geared Jupiter VIIIFs, and the final three production aircraft were replacement Mk IIs.
The Sidestrand inherited the good manoeuvrability of the Bourges, but despite proving to be an excellent aircraft for bombing and gunnery, only No. 101 Squadron was equipped. Three Sidestrand Mk Ills were converted to Sidestrand Mk V configuration but were then renamed Overstrand; these began to replace their predecessors in December 1934.

Can you tell me what colour the upper fuselage was painted? The black and white photo makes it look like the red used on the roundels . I beleive the main colour was silver.
Do you have any comments about this aircraft ?
